That's the second time ManOWar has changed the maps in the middle of rounds. It's pretty annoying as both times they were Cavalry maps then it switches them to Melee maps. I also lost my x4 from that round change though.
A question - why even make a change map poll? It's completely unnecessary and there was NOTHING wrong the map that it was currently on. Also, back when I was admin (unless the rules have changed) you're not suppose to mess with the map rotation UNLESS the map is broken in some way.
