Yeah, old tools werent so fine tuned. I was asked once to make an dust 2 forrest map, which I did by merging an wad from an already existing texture mod and doing some slight aligments and texture alterations to the original file. In the end I compiled it with out the need of an external wad but the game has a bug where it would , now get this, keep the textures loaded from the previous de_dust2 map just because both maps use the same texture names. The server was a dust2 only type of server and after changing from classic dust 2 to this one it kept old sand textures instead, only the skybox was different.
