[Mod] RPO Collection M20-21 part 1: Auto Bio Family Tracking + Auto step / in-law family tracking - Sims 4
Added 2025-01-04 22:51:45 +0000 UTC
Let's talk about the GENEALOGY tracking / DNA Testing System again
FULL ORIGINAL INFO POST ON WHAT I'M TALKING ABOUT
I mentioned this in my post of the new year, but in case you missed it, let me sum this up again. This stuff has been Partially done and sitting in my to do list for now a year, which is getting pretty stressful.
it was in one of its aspects / settings NEARLY releasable already, and has been for all this time. Due to how I've been so far unable to find time to finish it, I worked on making releasable the aspect of it that was already nearly ready as its own thing.
The M04 paternity mod update mentioned in the year-old post linked above has been in the same situation and hopefully will follow with a release soon.
So, What you ARE getting now:

automatic marking of family members: auto track and auto label for you up to great great grandparents / children, second cousins, first cousins twice removed / great grand aunts / nieces, and such. ("Choice A: all Sims automatically have their DNA in the database, and therefore, all relatives known = all relatives in existence.")
+ auto-tracking of 'marital' extended family for sims in committed relationships (not just married)
What You are NOT getting yet:
gameplay of having the sins discover their relatives through DNA testing, as opposed to auto labeling. ("Choice B: only Sims who decide to do DNA testing appear on the SimLines app and therefore only them exist in its database for other sims to find out a connection to them.")
WHY you aren't getting it yet: that system's core is mostly functional and has been for a year, BUT it does not have reactions, social interactions, etc, which are the parts that matter, so it's not ready to ship out.
gameplay around in-laws and step families.
WHY you aren't getting it yet: just nto done yet, part of all the planned RPO collection expansions
HOW THE FAMILY TRACKING WORKS:
You don't need to do anything particular, just putting the files in your mods folder and launching the game, the system will do its work. For the genetic family part, it will also retroactively apply on your existing sims automatically.
It's been given good testing, but this can be fairly COMPLEX / CONVOLUTED so if you notice problems or hiccups, please report!
distant family tracked by M20 shows in the 'family' filter of the Relationship Panel
Based on poll results:
since responders were near unanimous: added in law ans step family members to relationship panel 'family' tab
since responders were very split on this question: added settings to block (or not) romance between step family and / or in law family (in RPO global settings)

When installing this for the first time, it will retroactively read your exiting Sims to draw up their relationships. If you have huge amounts of Sims with lots of relations to each other, when FIRST loading a particular household after installing, the retroactive assigns can make that load screen longer.

DOWNLOAD:
- remove previous version
- grab the RPO Core Library if you don't have it;
- grab the file from this post and put it directly into your mods folder or one subfolder (it's a .package file, so, not extracting!)

Hi, nobody has reported this before, and now you and another person at once. This is odd and makes me wonder if some other mod has changed to cause this via interference, or if some other broken mod is causing issues. I would need to know more about your exact set up (what other mods you use etc) so we can rule out such interferences. If you are willing to help investigate your situation, come to the Discord server and we can look into all that in depth

2025-09-01 17:21:39 +0000 UTCIs there a way to cheat to add a relation? Some of my twins are coming up as step siblings as well
Jessica Richardson
2025-09-01 16:50:28 +0000 UTCI've been having issues with twins and triplets getting the step sibling trait

2025-08-31 04:21:24 +0000 UTCHi, this mod doesn't modify the family tree, but it does read from it, so if the game bugged out on the tree, it will impact what the mod says. If you can fix up your tree you can then re run the m20 calculations by using 'force recalculate' on the phone menu
Lumpinou
2025-04-25 21:47:42 +0000 UTCMy family tree is messed up for one of my sims. Her brother is listed as her Grandmother's brother and a Great Aunt as her sister. Her Mother isn't even listed in family tree. Her Great-grandfather is also listed as her father ( instead of mother) along with her actual father. So now all relationships are wrong, cousins listed as nieces and nephews. I tried to fix with Mccc but correct option are not available. I tried to reset with no luck. This was a same sex female couple who I used a brother as a surrogate. It was always somewhat correct in family tree, but after installing this update it's wrong. everyone else tree seems to be ok, just not this particular sim. Is there a cheat to fix? also could Adeepindigo's "family Connections" be interfering?
suzysim
2025-04-25 21:11:54 +0000 UTCHi, there are several layers here. First, whatever you see in the family tree - if that's where the issues start, ie, if things look wrong there, your problem is due to EA bugs which are known. Second, you'd have to check also that all your Mods are up to date
Lumpinou
2025-03-13 14:59:20 +0000 UTCHi! I'm having an issue with marrying into my sims family and the spouse being considered bio family. Since adding it to my game one of my sims got married and moved out with her spouse. I tried having them adopt a child and when the child was added to the family it saw one sim as a mom and the other as an aunt even though they were spouses not siblings. So I checked the profiles and it considered the in law as a sister and sister in law.
Rachel Fondeur
2025-03-13 03:42:48 +0000 UTCHi, there are no known errors, and I'd need to see your report file to be able to say anything about it - if you have Discord and can send it on the server that would be great! It is completely normal to see various EA processes and mods named in an errors detailed log, it only means they ran processes in your game - which they are built to do, so that alone is not an indication of much - one needs to look at the entire file
Lumpinou
2025-02-20 17:27:04 +0000 UTCI think this module is throwing out last exceptions with wicked whims installed, I'm not a modder, but the name of this module with the geneology was mentioned multiple times in the exception, I just want to know if its just me or has this happened with anyone else so far!
lexie
2025-02-20 17:02:02 +0000 UTCHi. Is it possible to have the relationships show when you hover over a sim in the relationship panel instead of only in the Sim Profile?
Megan MJ
2025-02-09 03:36:55 +0000 UTCHi, make sure you have no old files (run a scan on Mod Hound)
Lumpinou
2025-02-05 15:53:45 +0000 UTCHi, no, sometime this year
Lumpinou
2025-02-05 15:53:22 +0000 UTCI'm so confuse so is the DNA part ready because when I download it it shows up in mod folder and on the phone but when I click on the app it shows anything
Rebecca Rimpler
2025-02-05 08:07:58 +0000 UTCDo you know when gameplay around in-laws will be avail?
Olamide Afolabi
2025-02-04 20:45:46 +0000 UTChi, just wanted to report that this update did fix the child support loop for me! thanks for all your hard work as always :-)
jala
2025-01-22 19:07:11 +0000 UTCHi, try another browser
Lumpinou
2025-01-22 16:22:55 +0000 UTCIt won't let me download it just refreshes the page
alexandra bertrand
2025-01-22 12:21:51 +0000 UTCHi when you open the Sim's family tree from her perspective, do you see anything?
Lumpinou
2025-01-22 00:23:51 +0000 UTCWeird question, and I may not be doing it right; I have a sim who cannot "View All Living Relatives". The only option is to Recalculate. Her children and other family members can all "View Living Relatives", just not her.
E K
2025-01-21 23:21:54 +0000 UTCHi, what says what is outdated? Not sure what the rest would be about but we can help you further on discord by seeing some logs :)
Lumpinou
2025-01-20 17:08:50 +0000 UTCmy relative title isnt really popping up anymore. It no longer has the inlaw description... Im not sure whats going on is there maybe a conflicted mod? also M19 doesn't seem to work for me either it says outdated.
Damieka Henry
2025-01-20 14:47:38 +0000 UTChello, is there anything i can do to stop getting child support payment every sim 5 mins? I've gotten a few BE exception saying it has a bad tuning error.
charlene
2025-01-20 05:32:34 +0000 UTCyou're amazing, can't wait to try it out! Thanks so much <3
Estelle💫🤍
2025-01-20 01:29:05 +0000 UTCHi, from my end things should not conflict with anyone, not really able to
Lumpinou
2025-01-19 16:55:54 +0000 UTCthank you for your work. will this conflict with adeepindigo's friendandfamilyconnection?
My Goddess8
2025-01-19 15:52:51 +0000 UTCthank you so much for all your hard work! <3
Àmy Greig
2025-01-19 12:56:00 +0000 UTCHi, would need to see the report to be able to help you, you can post it on the discord :)
Lumpinou
2025-01-18 02:03:12 +0000 UTCHello my last exception report says that this is an old version, the v2.984 is the only version that i have installed
Exozxe
2025-01-18 01:37:56 +0000 UTCOK 🤔 I think technically the reason is that they're half siblings, so technically they are also the children of the partner of their parent without being their direct sister both ways, and that causes the system this 'confusion'. I will see what I can do about it
Lumpinou
2025-01-18 00:42:39 +0000 UTCAccording to the Mod Hound I have all the latest mods (I downloaded updated versions yesterday)
Emma Savitsky
2025-01-18 00:09:42 +0000 UTCNo I mean your mod files
Lumpinou
2025-01-18 00:04:18 +0000 UTCIt was a saved file from before the update. Do I need to create a new one?
Emma Savitsky
2025-01-18 00:00:07 +0000 UTCHi, when are your files from?
Lumpinou
2025-01-17 23:47:40 +0000 UTCHi, for some reason my sim's biological son has both the "son" and the "step-son" relationships. His half-sisters also have "sister" and "step-sister" in their relationships even though they live in different homes. Is there a way I can force correct this? The son is an infant so he does not have a phone.
Emma Savitsky
2025-01-17 22:58:49 +0000 UTCHi, would need to see the report to help you, you can send it on discord
Lumpinou
2025-01-17 16:23:06 +0000 UTCbetter exceptions keeps telling me this is an old version. i have no other rpo in any of my folders but this one.
Haley
2025-01-17 16:21:38 +0000 UTCHi, what are you referring to?
Lumpinou
2025-01-17 02:01:49 +0000 UTCI have that traits error also
Caren Joseph
2025-01-17 01:25:34 +0000 UTCYes i checked it and that is all fine. He was the one i picked out.
Vwduiven
2025-01-12 21:18:18 +0000 UTCThis is literally a must have mod! It's realistic and adds a lot to the game so it's not a hollow game. SO worth the early access! :) ♥ Perfect to pair with Pandasama's Childbirth Mod! :)
SimplyDeeSims
2025-01-12 09:12:35 +0000 UTCHi, sounds like you are thinking of Pandasama's mod
Lumpinou
2025-01-12 02:13:05 +0000 UTCI've updated but I can't call the OB & when I went to the hospital to give birth it was just the normal get to work hospital birth, all other aspects work fine though
Paige
2025-01-12 01:34:00 +0000 UTCHi, strange, one thing to check would be his ability to impregnate and his fertility, but I assume you chose him in the menus of the insemination, which usually would mean these things are fine
Lumpinou
2025-01-11 22:48:57 +0000 UTCHai, I love this new update and thank you so much. But my sim had a child with her partner through insemination. Now that the baby is here the father has no milestone of having a baby. And in the relationship panel it says it is his stepdaughter. Do you know why that is?
Vwduiven
2025-01-11 22:41:02 +0000 UTCThank you!
Manon B
2025-01-11 10:21:57 +0000 UTCHi, my end of things should not conflict with anything no
Lumpinou
2025-01-10 16:13:14 +0000 UTCThank you for this awesome update! Do you know if there's a possibility of it conflicting with Sacrificial's Life Manager mod, as it touches on the family tree and genetics too ? Have a nice weekend :)
Manon B
2025-01-10 15:03:44 +0000 UTCHi, I have updated and downloaded- I'm wondering where the paternity option has gone? :)
Elise
2025-01-09 15:07:01 +0000 UTCHi, yes, check under the 'what you are getting now' section for more info
Lumpinou
2025-01-08 16:17:53 +0000 UTCI'm a bit confused is this download for the family tracking or not?
Annirys Valdes
2025-01-08 07:07:56 +0000 UTCThank you so very much for this :D
JenJenLn
2025-01-08 04:46:11 +0000 UTCIn that case please send the error report so we can help you further :) There are no m19 errors in circulation that anyone knows of
Lumpinou
2025-01-07 18:57:07 +0000 UTCI downloaded the requirement it asked for though. I forgot the first time and I got a fatal error so I went back and downloaded it. I will try removing that module and see if I still get the broken trait error.
Josephine Miller
2025-01-07 18:19:08 +0000 UTCHi, you probably have the optional cas add on but are missing the requirement for it
Lumpinou
2025-01-07 16:39:05 +0000 UTCi keep getting a last exception from M19 saying the trait mod is broken. i have updated to the newest version and deleted everything from the old one and cleared all the cashes
Josephine Miller
2025-01-07 14:48:26 +0000 UTCHi, If you are updating, delete all package and script files of RPO mods and install the new ones. Setting files such as the global setting file and the custom Woohoo actions json file, you keep those
Lumpinou
2025-01-06 16:01:00 +0000 UTChola! cuál es el archivo M19 json? nunca he tenido ningun problema al instalar y ahora me da fallo.... yo tenia la version 2.982

Rachel Matos
2025-01-05 23:09:23 +0000 UTCHi, that is always an installation problem. We can help you sort it out on discord
Lumpinou
2025-01-05 16:45:23 +0000 UTCI have tthe same issue. With them in, im stuck on loadscreen, without, the game works well :)
Kaja80
2025-01-05 16:44:31 +0000 UTCThis will be game-changing! Thank you. <3
Marisa (gfvsims)
2025-01-05 05:07:27 +0000 UTCThis would be logical with an installation problem (wrong files somewhere, etc)
Lumpinou
2025-01-05 04:42:08 +0000 UTCOk thank you. Just to add. I just took out 20 and 21 but kept all other modules from this newest version in and all is well. Only happens with these two modules in.
Alexandria Walker
2025-01-05 04:41:34 +0000 UTCHi, sounds like an installation problem, we can help you more precisely on discord if we see some logs of your files
Lumpinou
2025-01-05 04:38:19 +0000 UTCHello. As always, thanks so much for your work. I’ve been away for a little bit and decided I wanted to do some updating. I usually don’t run into problems but upon updating to the most recent RPO to include modules 20 and 21 my game won’t load…sits on the plumbob screen forever. I made sure not to delete the settings file since I’m updating from 2.9+ When I put my previous version back in everything loaded as usual. The issue only happens when I put this version in. Any ideas what I may be doing wrong? Thank you.
Alexandria Walker
2025-01-05 04:22:39 +0000 UTCOK. Good to know! I'll put a different shower in and see if it works. :-)
ChelleBelle716
2025-01-05 03:54:39 +0000 UTCThanks! The Sims 4 is a very complex game and I couldn't do what the team does, but I am happy to try and do what I do!
Lumpinou
2025-01-05 03:48:04 +0000 UTCI probably mis read, but thank you for letting me know that it was in the game
Trisha
2025-01-05 02:45:56 +0000 UTCYou are a pure genius. I bet you can design your own games too. Happy New Year!
Faithie777
2025-01-05 02:45:55 +0000 UTCGlad to hear it! I might add another custom slot per Style eventually. As for locations - shower is enabled, maybe the exact shower objects you have are the matter? 🤔 Most Woohoo locations that seem compatible are enabled (the rocket is not because it leaves the ground and isn't click able, for example, but most others are in there)
Lumpinou
2025-01-05 02:44:14 +0000 UTCI love it!!! I put in all my customizations and it makes it so much more fun! I don't have WW so it's an awesome upgrade for me. :-) Do you plan on eventually making it available at all woohoo locations? I've been able to use it for the bed and a bush, but the options didn't come up when I tried to have them use the shower. I haven't tried anywhere other than those 3 so far.
ChelleBelle716
2025-01-05 02:42:05 +0000 UTCHi and thanks! Just in case I explained badly, in-law tracking is in the files already :)
Lumpinou
2025-01-05 02:38:46 +0000 UTCThis is amazing. Can’t wait for the auto in-law tracking. Keep up the good work ⭐️
Trisha
2025-01-05 02:35:43 +0000 UTCInteresting 🤔 can't really explain it as the core is told to ignore json. Lemme know if something gets iffy again. And I'm so glad to learn you like the interactive Woohoo features! You are the first person to say having used the custom interaction option so that made me glad someone found it usable haha
Lumpinou
2025-01-05 02:19:32 +0000 UTCI've been having a lot of fun with the interactive woohoo. My sims are exhausted. LOL
ChelleBelle716
2025-01-05 02:03:12 +0000 UTCSo when I first loaded a save file (and got the warning about the JSON), it was the save where I'd had the child support message issue and I did NOT have custom interactions set in that game, so maybe that had something to do with the message I got? I just put the JSON file back in my folder, restarted my game and loaded a save where I had custom interactions set and I did not get the warning message.
ChelleBelle716
2025-01-05 02:00:21 +0000 UTCI believe it definitely referenced the JSON file. I'll put it back in, relaunch and see what happens. It was also (other than my settings file) the only file I hadn't replaced.
ChelleBelle716
2025-01-05 01:48:48 +0000 UTCI still have it - I just moved it onto my desktop until I heard back from you. :-) Thank you!
ChelleBelle716
2025-01-05 01:47:43 +0000 UTCNot only that, but rpo Core knows to ignore json files when it does its version check 🤔 If you're on discord and can share a file log, I can see if you have an oldie hiding anywhere, this is a weird case
Lumpinou
2025-01-05 01:47:31 +0000 UTCAre you sure it was referring to the json? The json file should not carry a version number and therefore always be fine 🤔
Lumpinou
2025-01-05 01:46:42 +0000 UTCWhen I started the game with that, there was a pop up message saying that it was an old file and needed to be removed or there could be severe problems. It's ok to disregard that message with regards to that one file?
ChelleBelle716
2025-01-05 01:46:20 +0000 UTCThank you for the report!! Let's hope the fix did fix it, seems like it may be the case!
Lumpinou
2025-01-05 01:45:57 +0000 UTCIf it's still in your computer trash, you can go fetch it back!
Lumpinou
2025-01-05 01:45:24 +0000 UTCYes, forgot to mention but yes, it's basically the same as a setting file in that regard if you will. You can always keep it
Lumpinou
2025-01-05 01:45:04 +0000 UTCI also launched my save file from which I had sent you the info regarding the child support payment message spamming and that is no longer happening. If it happens again after the next child support payment, I'll let you know. Thank you!
ChelleBelle716
2025-01-05 01:44:44 +0000 UTCHi, you can absolutely keep your json file that stores your custom interactions
Lumpinou
2025-01-05 01:44:33 +0000 UTCOK. So I answered my own question about the Custom Woohoo Interactions file. I kept it in and when I launched my game it said to remove that file or there could be severe problems. So I did but, obviously, all the custom interactions I had set are now all gone. Will these always need to re-done when there is an update?
ChelleBelle716
2025-01-05 01:42:48 +0000 UTCHi! If we created custom interactive woohoo actions, it is ok to keep the "JSON" file along with our settings file?
ChelleBelle716
2025-01-05 01:00:00 +0000 UTComg you're amazing <333333

2025-01-05 00:31:04 +0000 UTCAmazing update, thank you!
Liyah
2025-01-05 00:14:02 +0000 UTCThank you so much for all of your hard work! Your mods are exceptional and make the game so much more interesting to play. You are so appreciated!
Trishax0ox
2025-01-04 23:40:52 +0000 UTCWith this update, it doesn't appear that identified family members filter into the family section of the relationships panels. Is this something that could be implemented? My sim knows who her grand-aunt is, for example, but when I click to view family members, she doesn't actually show up there. (simsmodelsimmer's mod does add them to that section when you create a family relationship, and I thought this update did the same thing, which is why I thought they might conflict)
Ashley
2025-01-04 23:40:49 +0000 UTCYou're amazing ! Thank you and Happy New Year !

Jaya
2025-01-04 23:23:29 +0000 UTCIf we see a system log, we can tell you precisely what's going on. Unfortunately without such info, I could only take wild guesses, if that makes sense
Lumpinou
2025-01-04 23:04:44 +0000 UTCIt was working and then I deleted a bunch of my mods to find out which one was breaking my game and then I fix my game and then ever since I’ve downloaded it back it’s not working and I’ve been through all the mods. There’s definitely no old ones on it.
Dylan Roselyn
2025-01-04 23:03:56 +0000 UTCHi, Check everywhere for old files if your setting don't show the new setting. We can help you further on discord!
Lumpinou
2025-01-04 23:01:28 +0000 UTCHi, no there's no reason why it would conflict with anything like that
Lumpinou
2025-01-04 23:01:05 +0000 UTCWow! I absolutely love this. Quick question, would this conflict with the Set Family Relationships mod by simsmodelsimmer? I'm unsure if that should even be a concern but I thought I'd ask!
Ashley
2025-01-04 22:56:07 +0000 UTCI am having trouble with the interactive woohoo it doesn't show up with the option to turn it on
