Good evening to all! 2 days ago while I was playing and everything was ok suddenly all graphics vanished and there was only the terrain with the hills, the sky and some birds flying around.. Nothing else.. No zombies, buildings, trees, cows nothing at all.. The problem is that I re installed everything but yet nothing changed.. Every time I join a game its just me the sky and the ground.. I don't know what else I can do to fix this... Please help if you have something in mind..!
