I'm having this problem, too. For me, the problem wasn't isolated to Britechester/being in university. This happens to all of my sims all the time
@justdancerebecca I've split your post into its own thread, since the thread you posted in was quite old and about Sims 3. Please describe your issue in more detail. Please also choose a new subject for your initial post that reflects your own issue. You can edit your first post to change the subject.
