So I join a fresh game and while the loaders are still loading I click that little upward arrow at the top left of screen to go to my main menu and the game freezes right there. I have to restart client via task manager and hope I get back in time to join it before I get an early leave and everyone abandons. I try not to do it anymore now but i still forget and occasionally freeze my game up during that loading session. Its fie after they are done loading and in hero select. I can leave to menu all I want then. Has been going on for at least a coupel months now.
