Oh, crap

[wrestlingdog]

So I just opened up my game and my university seems to have completely disappeared. I have no idea what happened. I was just playing it yesterday and it was working just fine. It had at least fifty young adults living in it that have completely vanished. I just have the one university, so I don't see how I could have deleted it. I haven't uploaded any new CC in months, and it was just the College Adjuster, the Batbox, and the Sim Blender.

Any ideas?
