This is not what you think it is. Rather than having pink and black error textures, when a map is loaded, that's all I see. The map is there, but instead of seeing it, a pink and black error texture is covering the screen. Originally I thought that it was something to do with the particle system, as that was producing a lot of errors, but I've found out that it isn't by fixing the particle_manifest. Please note that this mod was cracked to not use steam - hear me through on this - because it was built specifically for use by a certain individual (aka my neighbour) because it is just a brief tour around a made up castle for a homemade film. EDIT - Don't worry, I've fixed it.
