This is going to be fixed in the near future. I’m waiting to get a copy of the source-code for the vote plugin that we are running to modify and keep this from happening anymore so that we have a better rotation on the voting system.
Please just give us a little time to get it worked out.
Remember, the more a map is voted for, the more often it shows up right now. Basically if everyone votes Dust2 everytime it comes up, it’ll come up more often.
