There's an issue with the versus servers, and I'm hoping someone with more knowledge than I can help shed some light on. From time to time, they seem to revert to co-op mode, and as a result, have only 4 player slots available. Could anyone explain why this happens, and how to solve it when it occurs? I think it's related to Valve's dubious new server/lobby system, but I am speaking from a position of relative ignorance. I know that K3D was able to sort it out a couple of evenings ago, but don't know exactly what he did.

You are right thats what it is.

And will not go back to full 8 slot till all players are off the server and a admin has changed the map.

If you are about to mate I will talk you thought how it set up so you can do it your self.
