That's still a missing texture. To me, missing textures degrade the map.
Than make your own texture to put there. You can even make it hello kitty so the map is much upgraded.
This is an unofficial map, so I could care less. The only place it's going to be played is 1138. Sam didn't even provide a download link, nice one!
The most recent version should be put in his first post. I didn't even see those.
