My Teen Sim never goes to school. I used testingcheatsenabled to force her growth, because I wanted the parents to stay the same age while I gave the kids as much time as I wanted to grow up. I'm guessing that has something to do with it, but I still don't know how to fix the problem.
She grew into a Teen on a weekday, I believe, but it's been several days and she hasn't gone to school at all. School isn't under the list of workplaces, either, only her part time job is there.
Thanks a lot in advance!
