If you are getting these... more frequently than normal... turn the graphics down. This map throws a lot more in the game with over 2000 buildings. I can play it fine on my 7 year old laptop with lower settings. But my Uber desktop crashes when I use recommended settings. I drop them down & then have no issue.

Be wise with blocking roads too. If you block all access ways, your computer will ♥♥♥♥ itself trying to path find.

The map is stable, & has been running for over 2 years with only a small number of people have issues. You can try the winter version if you are having issues as I cut a lot out to allow for snow resource drain.
