Texture Problem!

I have a problem, as you know doubt can tell from ^this thread title^. This appears to only be happening on rp_blackmesaalpha. I spawn and see this:

Hoping that this will be gone once inside, I am greeted to this:

You’re supposed to take the bubble-wrap off when you take the map out of its box, of course. Silliness aside, my money’s on some sort of cubemap error. Does this happen every time you load the map?

yeah, but I played it a lot before and it didn’t do this until today.
