Left 4 Dead 2

Improved Bots (Advanced)
Issues with Singleplayer Versus
Everything works fine and I have done all the installation of this mod properly, however, the game decides to randomly crash or blackscreen during a campaign that is not a L4D1 campaign. (There are still a few in L4D1 section that do.) It happens randomly. Can you provide any fix or explanation? Thank you!
