Humorous Anecdotes

I don't know if this fits under Humorous Anecdotes or not, but it was weird. There was one Sim standing in front of the Dog Park. I couldn't interact with her. I couldn't reset her. I couldn't even delete her. She didn't move. She was like a statue. For three days now, my kids get the message about a field trip. The field trip never happens, but they get another one at the end of the day, which doesn't happen. I gave up, saved and exited, restarted the computer and reloaded the game. I was expecting the statue like Sim to be gone but she was still there, but at least she seemed to be active. All my Sims were at work/school, so nobody came to talk to her. Half an hour later she was still there, so I reset her. I also noticed a bunch of kids going to school between 10:30 and 11:00. They must have been stuck somewhere, somehow that didn't set of NRass 'Overwatch' (I think that's the one the sends messages about stuck Sims). I wonder what else was going wrong before I restarted.

Edit: I have no idea if this is related or not, but, since restarting, one of the town toddlers has learned to talk and walk. This is something I have never seen before. I get a message akin to "John Doe has increased their Learn To Talk to level 1". I regularly get messages that other sims have increased their skills, but never toddlers. I wish I'd saved the comment for a proper reference.
