After Brandi had 3 guys on my computer, I've married her to that black guy in Pleasantview (forgot his name :S ) and they had twin boys. Then, they had another boy. And then she was cheating on her husband with Don Lotario and she had twin boys again... Oh well.
Lovely! I found something nice for my lil' girls at last! I almost didn't make kids because I didn't have any pretty clothes for them... Now I have pretty clothes! The people of Sedona can thank you for kids now, before I didn't let them have kids... Because Maxis kids dresses are awful. But these are very nice!!!
Let me see... As many other I'd like ability to change shoes and own pregnant outfits. I'd also like that sims not only could get one or 2 kids but 3, 4 or 5.
I don't know how to get back what you've lost, but this was happening to me also. Try double-saving each time, better more then less they say. So the chance to loose everything is smaller. I don't know what else could you do. But it should stop after some time, at least it did at me. After - I don't know - maybe 3 months everything was saved properly after double-saving so I stopped double-saving and it all worked perfectly from then.
