Hey guys, I do not know if this will fix your issue or not but it might.
This is intended to maybe fix recent crashes that just started happening since 5.0. If you have bluescreens or crashes that have been an issue prior to 5.0, this likely won't help you but if your at your wits end...
1. Shutdown SimCity.
2. Go to “Program Files\Origin Games\SimCity\SimCity\UserData\Patches\UpdatedApp\” and copy all the files in that directory to “Program Files\Origin Games\SimCity\SimCity\” . Please note that this path is the default installation path for SimCity. Please modify this if you have custom installed SimCity.
3. Restart SimCity.
If you would be so kind to either PM me if it helped or respond here. This may or may not help.
