Please use this thread going forward: Partnered Sims turn into siblings | EA Forums - 4943482
I'm getting this as well. I've tested my game with and without mods (currently I require mods in my game to control other bugs, but removed them to see if this would still occur without mods). My main sim couple keep showing as both spouse, soul mates, and siblings. It's very annoying and I know of no way to fix it (MCCC doesn't work in this case) other than to reload down them for a gallery save (which means I then have to redo all of their relationships, and they currently have at least 40 living children, and the fix is only temporary.
One half of the couple is Grim. I use mods to make him a fully playable character, but can also play without mods and use cheat codes instead if I have to. The fact that removing mods made zero difference to this issue means I now have reinstalled my mods folder.
The Sims TeamMarked as Solution for Visibility. This is still an open issue.
If anyone of you are still encountering this (without mods), would you be willing to share your save file(s)? Preferably before and after the issue occurs.
If so, please send me a private message with a link to the file.

@TheSimsDirect, I have just started encountering this issue, and it is extremely frustrating. I do use CC and some mods, but based on what everyone else has been saying in this thread for more than 2 years, it obviously has nothing to do with mods or CC, and appears to relate to a CAS glitch, potentially one aggravated by spellcasters and/or scientists being present in the household. This has ruined my legacy save and I am extremely annoyed, having spent thousands of hours on this save, and severl hundred dollars on this game.
Are you able to acceot saves where mods and/or CC are used, please?
The Sims TeamHello @madsimmer91
The main reason we prefer to look at saves without mods/cc:is to be sure that any issues that we see in the save, whether it's the reported issue, or any other issues we encounter in the save, aren't due to mods/cc.
I've had the same issue (married couple turn into siblings) since last year, the problem here is I PLAY ON PS4. I checked the 12 forum pages before this one and I couldn't find anyone who played ps4 and fixed it. As far as I'm informed is not possible yet to use mods on The Sims 4 ps4 edition. Which leads to the conclussion I'm not using any mods and I don't even use cheats. This whole mess started when I used magic to clone my main sim and now she is "married" to her wife but also they're siblings. I also tried saving my family on the gallery so I could clone it all together and once I try to fix the relationships they can be turned back to married BUT then their children relationships get all messed up: one of their daughters turns into their niece, some of their other children turn into household members and I can't change it so that solution is a no-go. I don't know what else to do, please EA team help us! 😢
Hello! I'm also experiencing this bug, it seems to have happened after the latest infant update / growing together pack. I hope I'm doing this report thing correctly, I've never had to post on the forum before. I have attached a few screenshots to hopefully help the team understand what I'm seeing on my end.
Product: The Sims 4
Platform: PC
Which language are you playing the game in? English
How often does the bug occur? Every time (100%)
What is your current game version number? 1.96.397.1020
What expansions, game packs, and stuff packs do you have installed? Expansions - All *Game - All except Star Wars *Stuff - Spooky, Luxury Party, Moschino, Tiny Living, Laundry Day, Vintage Glamour, Cool Kitchen, Perfect Patio, Movie Hangout, and Fitness *Kits - Blooming Rooms, Courtyard Oasis, Throwback Fit, and Carnaval Streetwear
Steps: How can we find the bug ourselves? Have a young adult sim that has parents. Have young adult sim have a child with another sim. Marry a sim who is not the other parent to the new infant sim. Have new spouse adopt infant sim. After adopting, check the family tree, CAS, and relationship info panel and see that it has now made it so sim 1 (sim that had baby) and sim 2 (spouse, step-parent to infant) are now siblings! Along with that, the parents of sim 1 are now also showing as the parents of sim 2 in CAS, the family tree, and in the info panel.
What happens when the bug occurs? Bio. mom of the infant became siblings with her spouse (step-parent to infant) after the new spouse adopted the infant. The new spouse also automatically became the daughter of the bio. mom's parents. They are all in the same household. I cannot adjust the relationships in CAS, even with fulleditmode.
What do you expect to see? I would like to see the adopt function work correctly and have it so spouses don't become siblings after adopting their spouse's child, and so the family tree / relationships are the way they're supposed to be post-adoption.
Have you installed any customization with the game, e.g. Custom Content or Mods? Yes, but I have never had this issue prior to the new infant update.
Did this issue appear after a specific patch or change you made to your system? Yes - the latest infant update.
Please describe the patch or change you made. The adopt infant interaction that came with the latest update.
I've also had this issue - with the Robles family. There has been no cloning whatsoever, and I only noticed it right as Doli died and it said that Jay's *sister* had died! I was so bummed that it was basically too late to even fix the issue. So no, it's nothing to do with cloning - at least, that's not the core issue...I've never once cloned any sim, lol! Unfortunately, I don't know if this happened right after CAS editing, or if it was while I was rotationally playing with their adult children. Given the other comments, my best guess is that it was after going into CAS (I almost always have fulleditmode on, as well).
