Well...unfortunately, I have to revoke the praise I originally gave the festivals. :(
Turns out if one of the sims you're not actively playing (if you're a rotational type of player) happens to show up at the festival and autonomously buys a t-shirt, the festival t-shirt permanently overrides the first every day outfit you set for that sim in CAS...so, their primary outfit is gone if they happen to buy one of those t-shirts. I replaced all the premade families with families I created, so having sims' primary outfits replaced by festival t-shirts was kind of a big problem in my game.
I was mildly annoyed with the resting/sleeping in tents obsession sims had at the festival but decided to overlook it. Now, however, my active family is doing the same thing with their beds at home. I'm having to fight them to keep them from going to bed all day even though their energy bars are full.
So, I'm having to revert to a save from before the festival happened to undo all of this. This time, I won't send them to the festival so my non-active families' outfits don't get overridden and my sims will stop trying to sleep all day when they're not tired.
*Sigh*
