Its been messed with unnecessarily and without consultation to the community.
And that all future versions are simply an alterative and not a write over of the map.
I understand that a map with that many plays should maybe not be tempered with. But, it is his design / map and as far as I am aware he can do whatever he wants with it. It doesn't require community approval.
Not the map itself. We ask for the map creator Robustness to make the map Dualgap_fix_adaptive V9 playable and ranked.
I'll look into whether it is unranked or not.
edit: just because a newer version exists doesn't mean the old one is unranked. Unless the author or the vault team did that - which again is how we operate. The vault team didn't do it as far as I can see, so if the author unranked his old version then there isn't much more to be done.
I'd like to add that @Eternal is right - just because the map remains the same doesn't mean the game is too. There are balance patches and they move around the balance of Dual Gap too, as any other map.
