First, thank you guys at Stardock; your constant commitment and speedy responses to these problems are why I am sticking with this game (plus: it's just too much fun!)
I also get this white screen problem (just to clarify, is this white screen the fog of war?), but it seems some people still are able to get back in game. For me, the whole thing crashes and I shut down. Anyone else have this variant of the problem?
