I bought SimCity Complete Edition online.
Have been playing for a few weeks.
Suddenly one of the cities I have in my region will not load. When I go to region view and try to load it, the game crashes (I go back to my desktop) and the following message appears:
SimCity (TM) has stopped working.
A problem caused the program to stop working correctly.
Windows will close the program and notify you if a solution is available.
...And there is a button "Close program"
I am running Windows 10 in a brand new Toshiba i7 laptop with AMD Radeon Graphics.
