If the Badlands exploit becomes a major problem, here's a temporary fix until Valve fixes it.
Download this:
http://theville2.org/tf2/maps/cp_badlands.bsp.bz2And replace it with the cp_badlands on the server.
That will put a barrel in the spot needed to stand to be able to get out of the map.
It does
not require clients to download the map again, "as the Entity section of the map only needs to be on the
server."
Again, this should just be a last resort if the exploit becomes very constantly exploited. (But now that it's as easy as a download and an upload, why not)
