I have a problem, whenever game gets minimized (while connected to server) and back to view, screen is black and I need to restart it. all would be fine (to avoid it just don't press START button. but yesterday one of the trial programs popped out an ad and got my game down just in time when I alerted super zombie and was about to reach safe place to kill him. I don't mind getting eaten by zombies. but losing survival backpack is just annoying.
