I have been playing The Sims 3 since it came out with no problems or CC, but here recently I have been having a glitch occuring with my family tree. It goes like this: I make 2 married adults and after a while of playing they suddenly aren't married anymore or divorced and if they have kids their kids are usually with strange people or even other family members. One time I had a child in a relationship with her dad. Sometimes they aren't even a couple; under partner on the family tree it says they are best friends with a random person. I wouldn't care so much if they could break up or be with someone else instead, but they can't. Another time I had an engaged couple but the family tree messed up and she was partners with her brother thus making it impossible for them to get married. Any ideas on how to fix this?
