Left 4 Dead 2 - The Last Stand SourceMod crash
 

Hey guys!
I have been having this issue where when I install SourceMod without plugins on The Last Stand updates, the game would run fine but whenever I add just one plugin on it, it crashes somewhere between 60% and 80% when loading a map. It appears to crash only on The Last Stand updates because when I tested it on a cracked 2.1.4.7 copy of the game, it works (but installing some mods crash it too)

Am I missing some extensions or anything?
