I've had this problem since I downloaded the game. I go to university, and I don't receive any bills even though I'm supposed to. The mailman comes, hangs near the mailbox, and leaves without doing anything. The normal neighborhood is fine and the mailman does his job properly. I only ask about this because I haven't seen anyone mention a solution to this problem, if there even is one. Is there anything I can do to fix this?

Do up your dorm in build and build mode, he leaves no bills I think to everything depreciating. It's not like they own their rooms like sims do their own home.
