Your city is not processing properly
After playing my city for a while I got the error below:
"Your city is not processing properly. We would like to try to repair it. This process will take you back to the main menu."
I hit Quit, much to my shagrin as this was the only option, and it removed me from the game. I then had the option to rollback. I did that, and found that it has only set me back a bit, so I didn't worry.
I then prceeded to have this happen 6 more times, any where from 5 to 15 minute after rolling back and reopening the map, and it always set me back to the exact same place. It seems to always happen shortly after I hit 5k people and upgrade my city hall.
I will be attempting to star a new city on a new region to test. I'd much prefer to keep this first city going if possible. Any help is appreciated.
Edit - New region worked for some time but the error just started with this new region as well.
