A few minutes into playing after updating, my sim gets a call from her cousin to say that the cousin is now in a relationship with her own brother. I went into the other family to check and sure enou...
Ideas
Also experiencing this issue on PC. It's not mod related as far as I can tell. I think it started when I went into CAS to check something. I came out and all of a sudden my legacy heir of like ten generations can't do any romantic interactions with her wife. I'd heard about this issue yesterday so I checked to see if they were suddenly siblings, and indeed it's the case. I've tried resetting their relationship with MCCC to no avail. I really don't want to move them to a new save because I don't want to lose my progress with their business... I'll keep trying different things and if anything works I'll come back and reply.
Ok, I tried a lot of cheaty stuff and I wasn't able to fix it, so I did have to make fresh copies of the Sims. Here's what I did:
- Saved my family in their current state to my library.
- Copied the family to three separate empty lots in Newcrest.
- In one of the lots, I deleted all but one of the problem Sims and created dummy parents for her.
- I repeated for the other problem Sim on a different lot.
- In the third lot, I deleted everyone but their kid.
- I made the fresh copies of my problem Sims meet, cheated their friendship and romantic relationships to maximum, and had them get married.
- I split them into their own household, and then I merged it with the one that just has their kid.
- With CAS full edit mode, I set their kid's relationship.
- I evicted the glitched version of the household and replaced it with the one I just created in Newcrest.
- Finally, I had to create their family business again and cheat it to where it was.
I think this way is better than some of the other ones I've seen suggested here because it'll save all your Sims' traits and milestones and even aspiration progress and you don't have to find a backup version. As far as I can tell, it's working okay and it hasn't come back yet.
I don't think this glitch was caused by the fact that one of them didn't have parents in game, but based on some of the other posts in here I do suspect that it did allow it to happen. Regardless, this was a huge pain to solve and was actually devastating to me to discover the glitch so I really hope they fix whatever's causing this soon.
I want to try this, the problem is one of my sims actually has a mom in game already. I wonder if I create a copy with dummy parents for the sim WITHOUT parents, keep the existing sim who has a parent but delete his relationships with his partner & kids, and create a copy with just the kids. Hm. Will try this and report back. This bug is making everything so convoluted and annoying 😓
