This one isn't a bug, but I thought it was interesting: I put a roller skating rink in the yard of one of my houses and sent a kid out to skate. He was out there for hours, but I didn't think anything of it until a message popped up indicating that the kid was getting too hot, and if I didn't cool him down, I might get a visit from the social worker. So can we gather from this that exercise causes Sims' body temperature to go up? It was springtime on this lot when it happened, so I wasn't expecting any heat-related problems.
That's funny that you should mention that. One of my sim kids decided to go to the ever popular jumping on the bed for hours (shouldn't the springs break at some point?) - ANYway... I also got the message stating the my sim kid was over heated...
Oh well.
