Hello! I am trying to make a map and every time I try to put the heightmap into the mapmaker, it crashes. I use Paint Tool SAI and then I open it in Paint.net and turn it to grayscale. Even after I do that, FH comes up with the Feralheart has stopped working message. I really am at a loss of what to do... I made sure that the capitals are correct, it is a .png, and in grayscale. Any help is appreciated!
