Re: flashlight does not work in MONORAIL SKYBRIDGE.
I just got this bug today. Came around a corner and went to raise my flashlight and everthing froze. I thought my comp had locked up and just as I was about to do the Ctrl-Alt-Del thing the game suddenly came back to life but without any light. Just like the above screenshot.
I just exited game and restarted. Everything was fine after that.
