Forum:Why won't they go??

I have three teenagers in my Sims 3 game, they are girl triplets. In my game it was a Friday morning at 8.00 am and one of them got on the school bus, the other two didn't. So I pressed the "go to school" button and a message popped up saying "School Not in Session" Well if it was not in session how come one of them went and was in school? Also on the "School" tab it said that the next time they had to go to school was in three days as if it had totally forgotten about Friday! Has this happened to anyone else, and, why? --86.154.7.213 14:13, July 23, 2011 (UTC)
