Notice: It is on gray-scale, square and png. format, in one layer.
It seems no matter how many times I try to get it to work in-game, it closes the game instantly I try to open it in-game (in other words, it crashes). I was planning on making my own map, only my mask works.
Anything I'm doing wrong? I know I made a topic like this (but with preset help), but this is on the new updated version of the game and I am utterly confused (and frustrated, because I was planning on making this a public map).
