The game starts up fine and when it goes to the menu background it will display this. I purchased the standalone when it first became available on steam and the error didn't occur. After the 2nd or 3rd update it permanently switched to this. Sometimes I can see certain textures such as the grass and a few trees and the rest is grey. Most of the time, the menu screen background is all greyed out besides the menu buttons. {F30352}
