good game but a few bugs ...

I am a real fan of Sims 3, I have all the additional drives. the fact that my sims can have animals I think it's great but here it is: the additional disk caused me problems in my game, in fact, when my sims (I do not control) have children, they will soon disappear they become toddlers because instead of having characters "human" traits of the characters they have traits "animals". but that's not all, by dint of playing, my sims do vieillisent even more ... so I decided to remove the add disk, and since my game is perfect, everything works.
