LE: trying to restore career event

When do you get the LE ? Does anything visible happen in the game ?

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.

Turns out, it's the same like you reported yesterday. I've merged your posts.

The LE on restarting a save on exam day (which was also Love Day) in the unmodded game looks similar if not the same as the LE on restarting a modded game on a regular school day that fell on Lottery Day. I suspect that this is due to the decision to use the holiday system to revamp the active school days, and the scheduled holiday is overriding the active school day, preventing it from being displayed/affecting school performance. So the fix for multiple teen sims not being able to participate in active school days broke active school days on holidays.

I don't know why the Better Exceptions section mentions bad CC, I don't have any CC (just mods) and the BE-ExceptionReport.html doesn't identify any broken mods/CC.
