the game server has booted me a few times, and i have logged out a few times to make this happen. The main menu loads and all you see behind the main menu options is a grey scale of colors segregated, upon loading into the game the screen is still looking as such and so far the only thing i have found to fix the issue is pressing tab to bring up inventory. I have tried logging out and back in and that has not worked. I have not tried shutting down the game and restarting since pulling up my inventory seems to remedy the problem.
