It's normal that the plugin fails itself when the server starts because sometimes server config cvars don't have any effect until the next map change. This happens mostly with mp_teamlist and mp_teamplay.
In any case, make sure you are using the latest HLDS from SteamCmd or ReHLDS, I think the latest builds start with 8xxx (example Build 824
. Also try to use BugfixedHL which fixes some bugs and improves gameplay.
