-Fixed major crash issue on map 3 where are corrupted stair-case model was drawing heavily on system resources. Computers with low-graphics settings in L4D2 would crash the game as it did not have a high enough threshold of system resources to work with
-Extended escape timer on map 5 by an additional minute
-Reworked laser grid in map 2 to improve appearance and minigame
