So awhile back I got into CMSF2. Loved the game. But one day I booted it up (vanilla, all DLC, also Steam copy) went into quick battle, and all the buildings, trees, buildings, and pixeltruppen were floating in a black void. Then I noticed my UI was part of the void and that I couldn't interact with it. It's like this between games, so it's and issue between the CM engine and my system me thinks but I'm not very tech savy and was hoping to find help here.
