Missing texture

[Fazolki]

When using this download as a replacement for the workshop one, when I become the hidden my entire screen is just pink and black squares... (missing textures)
It isn't the map cause they have always worked before, it is the overlay of the hidden character I think... Any fixes?

@Stickymitts The GitHub version doesn't have the necessary materials, sounds and models for the gamemode by itself. You can get all of that if you extract the Workshop version using the gmad extractor from your /GarrysMod/bin folder then placing them in the correct directories.
