FIX THE NO MERCY ELEVATOR GLITCH ALREADY!
How long has this glitch been present?
I had two very close games ruined by this glitch tonight. One in which a team mate fell through the floor and died and another in which my entire team fell through the floor and died.
I can't imagine it's a terribly difficult glitch to fix given that other campaigns have elevators which work perfectly fine (Dead Center, for example). This glitch has been present since the level was imported from L4D1 and it's never been fixed (other than disabling jump, which doesn't work 100% as you can still die if you are incapped in the elevator or if you heal, or even just seemingly at random and for no reason).
Please fix it. I can't really count the number of games which have been ruined by this. It's especially frustrating when it's a close game, too, which are rare enough to find given the number of rage quits. So it really sucks when you finally find a good, close, game only to have one team completely handicapped by people falling through the elevator floor and dying.
This is simple stuff which should have been fixed ages ago, so I don't understand why this bug has persisted for so long (especially since "No Mercy" is probably the single most played campaign in the entire game).
