Calendar is broken after getaway

bewitchedbard​  I had a very similar experience sending a child to Getaway.

I wish I had better news.  It seriously impacted my game and still does.  
Consider going back to a previous save before you sent the child to Getaway.  
In hindsight I should have exited without saving or loaded an earlier save.  I didn't notice all of the problems the glitch caused right away.

I'm on PC and I tried Verifying Files on Steam.  The Clean Folder.  I checked my calendar settings in game menu.  All looked normal / default.  After one of the game updates the moon phases on the calendar started working again.  Nothing I did - it just started working.  So, the glitch corrupted my legacy game save.  

Sims joining a new career after the glitch will go to work as usual.
Sims that had a job when the glitch happened would not go to work. They still got paid but could not get promoted or work on advancing.  The only workaround I found was for them to quit the job and start again.  
I have a global superstar actor that is still glitched and won't go to acting jobs.  He just got his walk of fame star. ?!!  I think I'm going to have him quit and see if he keeps his fame - or not.  

Since the glitch I never see a mailman.  I don't receive any heirlooms or any of the bonus stuff that gets delivered thru mail.
