I'll be playing the game and it will be running fine then the screen will freeze up. I can still hear everything in the background, I can move my mouse and make clicks and hear the game working but the visuals are all frozen. I was able to close out and restart the game and play on but now it freezes every couple of minutes and I loose any progress.
Basically unplayable for me at the moment and sadly it's becoming a waste of $20 bucks. I know others have this problem from reading other sites but no one has any solutions.
Load the game, choose a new duplicate and/or open up a build selection tab or similar. Doesn't happen every time but mostly then.
