[L4D2] coop problems (player count?)

[Ashlou]

So, we just got a server set up, and usually we play versus on it. However, we went to play a community made map on coop, which worked fine... except for two things.
1. SI respawn timer was really low.
2. When we voted to restart the map, even if all four of us pressed f1, it said "vote failed." However, if we voted to return to the lobby it succeeded.

This leads me to believe there was something off about the coop player count.

The server is running Metamod and Sourcemod.

Any ideas as to what we can do to fix it?
