Water textures on ZF_OutsetIsland

OutsetIsland seems to be missing underwater textures.

Dunno what's up it worked fine the last time I was on this map.
Water looks fine until you go underneath the surface, then this happens and you're swimming blind until you resurface.

That actually happens on many maps and isn't just limited to that one, I think restarting TF2 sometimes fixes it.

Okay happened on every map, verifying my cache fixed it.

i know this is wrong but when ever its on cactus templem in firstperson the water turned purple and black but in the one map with teh water room that u can open by something it will turn to black,white or just negitve colors
