As I mentioned earlier in this thread, I'm having a problem with the Mann vs Machine gamemode. Whenever the tank robot bursts through the barricade, the game has a chance of crashing with the standard "hl2.exe has stopped working" message pop-up. Sometimes I'm lucky and the game doesn't crash, but nine times out of ten it will. It tends to happen at different moments each time, sometimes crashing almost immediately after (and sometimes before) the barricade's exploded and sometimes while the last of the rubble is raining down in small, splintery chunks, and at one point the game even crashed when the tank was nearing the bomb site. This happens on all of the maps. Is anyone else getting this problem and how can I fix it? It's getting rather frustrating.
