Everytime I save a map, it does not appear in crafted maps

ive tried recreating to no avail, even made a map from scratch

Dont know much about the editor but did you press the burn option

if it does not appear, from my test it is that the players are badly initialized

Did you do Advanced Mode, Intermediate or Beginner?
I had the same issue when I did, “Advanced” option.
I think much of it has to do with not knowing how to build it to the point where it does show up in the game. What I did instead was use the “Beginner” option - which worked out great and saved me a ton of time. Has the out-of-bounds border decorations all set up. Things that would have taken me hours to build.
