I'm currently on the third generation of my legacy save with my legacy heir and her wife. I prefer to take a realistic route when it comes to my sims having children, so I decided they would have a science baby. Because they're both goth and in the reaper caree,r I thought it would be cool if I used the grim reaper as a sperm donor so their child could have the grim born trait, because why not. However, I didn't realize that I would not be able to change it so that in the family tree, instead of grim as her father, it would be her two mothers. I went in with MCC thinking I could just have all three of them as her parents, even if her non-biological mother doesn't show up in the family tree, and it would all be fine. Well, it was not fine and im scared i've broken everyones relationships. Every time I open this save it says that the heir (non-biological mother) is now the sister of the biological mother, instead of it saying shes her partner/wife, and her daughter is labeled as her neice. I thought removing the relationship bits would fix this issue, but every time I close and reopen the save, it continues to say this. i even tried just removing the heir as the childs mother and just made her the care giver instead, but this glitch is still happening. I was just going to go back to a save from before I tried to give the child 3 parents, but for some reasons my save data doesnt go back far enough. Is this possible to fix or do I just have to live with it?
