Changing the config option "non_repeating_maps" from false to true will prevent players from voting on the currently played map during the map vote.
Paradise has an unhealthy attachment to Box which stems it being the only playable map for the vast majority of this communities life. Our other maps will never updated, made better, or otherwise fixed if no one ever plays them. And when someone does try to fix one of our maps that isn't Box it can be highly demoralizing when those countless hours spent mapping are essentially wasted as it goes completely unused.
For me at least I think the most frustrating part is that our other maps Delta and Meta aren't even bad or broken, it's just everyone is stuck in their ways with Box and refuse to vote for anything else. To be honest, this is going to force peoples hands a bit, and there will probably be people complain about having to play other maps, but we've been playing Box for the past nine years, so I think it's about time we give other maps a shot.
This monotonous cycle of Box Box Box Box Box needs to be broken and this is one very easy way to do it, it's as simple as changing a config option from false to true.
