Main Save Household Problems

I’ve managed to open the game with no problems at all but for some reason in one of my save (my main save I’ve been playing for two years now 💔) all of my households have completely dissapeared. My mods, builds and other saves are working completely fine but just all of these specific households are gone and I don’t have a backup anymore since it got corrupted and I didn’t manage to create a new one in time before this happened
