[HSY] LE: 'Exception raised while trying to restore career event'

Since I don't have mods enabled, so don't get reports from Better Exceptions or MCCC when the LE occurs, I don't know exactly when they occurred. I didn't notice them until I exited the game and checked PlumbBuddy. Things I did this game session: Logged in at the beginning of exam day (exam day event UI not present), completed the school day (did not get any school performance change), went on a weekend trip to Selvadorado excavating several dig piles and the temple, returned home, invited Cassandra Goth over and did homework, went to school on Monday. My best guess is that the LE occurred on Friday as it's the only thing that seems to fit the error text.
