I've tried a bunch of different things to keep my peeps asleep. I praise them for going to bed when they're tired and try to keep them from napping during the day when they don't really need to (aren't tired).

I've noticed when I close the game and reopen it, even if it was paused or not, they'll be up and running around again, and then head to bed immediately, and will still be exhausted.

This is version 1.00.05, I just got the game yesterday in fact.

Also... my store is only updating like once a day or something. I bought things yesterday, and then today, and it's been about 12 hours since I woke up this morning and it still hasn't updated.
