World starts turning dark during gameplay. Except where the sun shines. Will completely cover buildings and inside buildings, tunnels, etc. Starts about 30 minutes after game start. Gets worse after. Shutting down and restarting fixes it, then it repeats again. Torches only light the block it is on.
