Just a Few Lines of Code...

By changing just a few lines of code, it's possible to re-enable the "crawler rounds" that were intended initially for this map; only nova crawlers will spawn for the entire round, which incidentally turns dining room into a 2 spawn (even if the top door is open). This would make it the fastest instas strat ever.

Unfortunately, if you try this, you will crash if the game is trying to spawn crawlers while you stand in a zone with no crawler spawns/enabled crawler spawns (i.e. alley), so if you want to go to alley, you can't kill any crawlers or let them bleed out without risking a crash, and it happens very quickly.
