On my surf server evrything was fine so I went afk for a bit came back to it on de_dust so I changed the map and tried to join the server and this is the console.log and its in there a bunch of times. It also wont let me join the server.
We use mapchooser extended. It gives you back the ability to simply use mapcycle.txt in your csgo folder so you don't have to mess with the crappy mapgroups.
To disable the games default map voting all you should need to do is put this in your server.cfg: sv_allow_votes 0
