Missing a source, but what source?

[silk pasture]

I have CSS, so that's not the problem I believe.
If it is though, I might have to check up on it, but a lot of everything except the skybox works fine.

What source game does this map (mu_gmall) need for its skybox?

Please ping if I get a response, d'appreciate it.

Do you have Team Fortress 2, Half Life 2: Episode 2 and Left 4 Dead 2 installed and mounted?
