Re: [ARCHIVED] Partnered Sims turn into siblings/family relationships

I’m not sure if anybody has managed to find a fix for this, but I had the same issue and I’ve found a way around the bug and now my affected sims can perform romantic interactions again, even after going into CAS.

Firstly I used the command center mod to permanently delete any duplicate sims that had been created by my spellcaster. 

Next I used simsmodelsimmer’s set family relationship mod to remove the sibling relationship between my two affected sims.

Finally I created four new sims in CAS, summoned them to my sim’s home lot and used command center to set them as parents to my affected couple. Just to be sure I also used set family relationship to make them in-laws to the other sim too.

After this I used command centre to kill the parents so they’d stay in my family tree, saved my game and checked on my sims. The sibling relationship was removed and they no longer had a shared mystery parent. I went into CAS and upon exiting they were still able to perform romantic interactions, and in the sims panel they’re once again only listed as spouses.

I didn’t have to delete any relationships or move my sims out so they still retained all their sentiments etc. I’m not sure if the fix is totally permanent but seeing as CAS hasn’t caused their relationship to revert again I’d say it’s as good as it gets.

My gameplay is exactly the same as before, only difference is my married couple now have parents. I’m not sure if this fix works for sims born in game that already have parents in their family tree, but I think the bug is mainly caused by at least one sim not having parents.

Hope this helps!
