Is there some special kind of tagging or something I have to do in order to make my map accessible? I designed a map to resemble Nephra's stage from Cardinal Syn, it's not a perfect 1:1 model (yet) but it's the first stage I made in this game.

However, I cannot access it or download it to play it in my own game. What do?
