No surprise that I'm back d:
Anyway, I got the new version of GIMP, and I made a terrain in it. Now, in this GIMP, you have to export to save as a .png. I can't use the exported .pngs in the MapMaker, as it'll freeze. The one time I DID get it to work, the corners of the map went up into the sky, like there were two giant poles.
