it may possibly have somthing to do with a mod interferring, like a particle mod or such. many mods from my knowledge interfeir with this mod, like wac, hvap, and many others.usually when its squared like that it is a missing texture, possibly from missing content or a mod. also, what map is that? i always wanted to download that map but never could find it...

also, check your files.

ok i will try, and the map is gm_fork

thanks so much for the map!
