nevermind I got 😉 it worked
1. Go to your Documents\Electronic Arts\The Sims 3\Saves folder.
2. Go into the save folder you are having the problems on.
3. Delete the file
The only thing about using this workaround is that if you have friends at the university already, it creates a new university, so the sims you meet at the new university will be duplicates, and will NOT have the relationships you had before.
