Yes

I have some questions, I have counter strike source, and even global offensive, both mounted, all the textures are downloaded, I've triple checked that, yet nothing works. I like this map very much, and it use to work a little bit, but now it's basically errors.

For me this map used to work but the chairs were missing textures, now the ENTIRE MAP is errors and missing textures.
