All Sims get Stuck

I hope this upcoming update fixes this, I doubt it, but it's quite a nuisance. All my Sims get stuck doing various actions, and nothing seems to help. They twitch out cancelling interactions a lot. I'm not sure which update caused this, whether it was the game or EA app. They eventually get unstuck, but not after quite some time has passed. Ruins interactions, makes them late for everything, and UGH. Whether they're fully automated or not, this happens. Resetting each Sim doesn't help. Forcing the house to reset doesn't help. Deleting cache files doesn't help. Aside from moving them completely out of the house and back in, I don't know what else to do or why this is happening.

It is a large mansion in the Ondarion neighborhood, if that helps. I have all expansions, game packs, stuff packs and kits. A decent gaming computer running this game and it seems the bigger TS4 gets, the more my Sims twitch out. Sims in smaller houses do this, too. HELP!
