If you are getting these... more frequently than normal... turn the graphics down. This mod throws a lot more in the game. 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.
