RedSec Under Map Glitch

I've played several RedSec games, and out of 6 wins, 2 of them had the first place robbed by people glitching under the map and surviving until the very end because they're untouched the entire game. The frequency is really what's killing the game mode. It's really demoralizing and my multiple friends are refusing to play Redsec until it's fixed (rightfully so).

This link is to one of several youtube videos actively encouraging glitching out of the map. The strategy can be seen here, and I really hope this is fixed quickly. RedSec is fun but I don't want to have the entire match lead up to a cheesed second place. You can't even report them because if you get second place, the match just ends and you can't go to a profile.
