I have the same problem, I can't send any of them to university or move any Sims to a new house without this happening and it started after the update that included moving to a new town. Im glad I'm not the only one with this problem.
Would really appreciate help in fixing this problem thanks.
I had this problem, and posted on here, someone helped me and gave me this link to what you can do to fix it, http://answers.ea.com/t5/The-Sims-3/FAQ-Troubleshooting-Steps/td-p/714
Thought I'd help because I hated this problem and was so happy to have it fixed!
