Can't get custom map to work with sv_changemap. This is the error its giving.

I tried adding all three to my DEV server (repro'd this behavior on Chuckle before removing the mods there):

http://steamcommunity.com/sharedfile...s/?id=78917836
http://steamcommunity.com/sharedfile...s/?id=75943673

They all load just fine (that is, I can connect w/o error using my client) if they're specified as the server start map. They all fail with this error when I use sv_changemap (or the Web Admin GUI) to change maps to them:
