I can't run this map for some inexplanatory reason.

Whenever I load it like any other custom map (in any way; on a private listen server, or a pub server) my game crashes.

I haven't tried the other JM map, Offices yet, as I don't have it, but whenever I try running the map on a public server, the entire server crashes along with my game.
These maps have got a problem, it looks like!

Or... is there a fix for it I'm not aware of?
