I've been having this issue after I loaded up the game this morning. Everything was fine, but when I pressed "go on duty" something strange happened. Textures of everything were just dissapearing and I couldn't even see where I was going. I googled and it's just the common texture glitch/bug. But it only appears when I'm on duty and I've never had it before. Does anyone know what it could be? I tried to lower my settings and change priority etc. but it just doesn't work and the game is unplayable... Any suggestions?
