Hmm, I just tried to make a map offline, which made black squares diagonally from the top left all the way down to the bottom right of the world...I have tried several times.
But my levels dont look like yours, Wan, in the black areas...they are the correct levels, and they auto complete when I walk on them, but even if I walk through all the black squares, and let the map auto-fill, then try to make the map again it comes out the same....
