Okay, I was having (several) issues with my sleep deprived VF Families (even with both patches). They wouldn't stay asleep (would get up at a quarter bar), they wouldn't nap unless it was a quarter-ish bar...and it was quite consistant. Tried many many things... (and I am very nice with them, fruits, organic, rest, everything lol)
I tried something new today, though, and it seems to of 'solved' my issues for the most part.
I always pause (was before too) if I'm going to be gone for a while. Then like an hour or so before I play, I unpause the game (was before too) shut it off, and come back later.
But that wasn't helping before at all either... but today I deleted all my families (cry) and made my families anew... It seems to of solved it pretty well. Maybe try it with just one family, see how it works for you. I deleted all of them, though. Not sure, but I think the 'games' kept the memory of the current families (or something, I don't know, I don't design, lol I just play :p)
Either way, they seem to rest more, the bar goes up more, and they are generally happier too.
Hope this helps someone at least ^_^
