I have been working on a map for my campaign for hours. I have had to rebuild once already. The screen map blacked out and when I tried to recover it, I was unsuccessful. It then reverted to the first save I made. Now, I am close to finishing my second attempt at making the map, and I am now getting an unsupported brush error. I try to go to the map before I started painting it and I cannot access it either. Pretty annoyed and am here to vent. Don't know if much can be done. Sent error to support.
