Stuck Sims?! Help

Weirdly, I updated the game and had no issues. I played for about an hour, came back from 'vacation', and suddenly my sim was stuck on her command to go use the toilet. Wouldn't respond to anything, reset sim didn't work. Couldn't even click another sim. They all froze in their actions and I couldn't select a different sim to play. 

I messed with the game for like an hour. Took my mods out, repaired the game - did a few variations of that for awhile. Kept having the same problem. I ended up having to revert to my previous save and lost the hour I'd played. I was able to keep my mods in (minus the ones that actually do need updates). Very weird. Prior to this I had a problem out of nowhere with my sims freezing (and freezing everyone else) if anyone interacted with a bar. Didn't update, didn't download anything new. It randomly stopped happening after two real life days of play.
