I play CS: Source a lot especially with bots, and I got bored of the official maps, so I want to play custom ones with bots. But when I (If I am right) play alone the map works perfectly but when I want to play with bots It starts to sample walkable space. Before even half of the bar is finished It freezes my game so I have to close it. Custom maps obviously work in servers made by other people but I really want to shoot terrorists instead of shooting zombies (I play zombie plague a lot...). Any help is appreciated, thanks.
