puzzlezaddictThank you for helping. I copied the whole folders of "Characters" and "Houses" and a file "Neighborhood.iff" to that new UserData folder, and it did restore my family/house but unfortunately it doesn't work. Still crashes after less than a minute. Should I try copying only specific files from those folders? If so, which ones should I look for?
It seems like the crash is strictly connected with my family, as now I tried some basegame family household and it didn't crash. It doesn't crash in the menu, map or build/buy mode. Only on gameplay, when the time goes. I'm 100% sure it's about interactions between my sim (the family I play long time) and a dog/cat/any pet. I put a sign "no pets" and it fixed the problem at least temporaily. Still, if a stray comes and begs for attention, it crashes.
