Apart from the school problem, I'm having a problem with one specific sim: She keeps twirling, like if she was changing outfits but without doing so, and never does anything else as she's told. (except walking to some place, using the computer or reading books). In fact, the interactions totally vanish once she twirls (not the menu, the square on the top when you send some sim to do something). This happened after a few hours of totally stable game (apart from the school thing, of course). About that sim: She had just finished writing a book and I sent her to change her baby's diaper when it first occurred. Then it started happening, like I said, non-stop. She was wearing underwear. I tried to reload her, the lot and the entire neighborhood, nothing solves it.

I haven't been able to recreate this on a vanilla game, but, since this doesn't happen to all sims and it happened after hours of normal game with the latest version of AM, I can't be sure if it's a game bug or AM-related.

This happened to me too. Also, my sim was at work, it was supposed to end at 13:30, but once I started the game (it was around 10 sim-time), the pop-up that appears at the end of the work-day appeared, my sim got out of the building along with all his colleagues and he was flagged with "skipping work". No matter how many times I tried to send him back, he just wouldn't go to work again.
