Yes, I called it WildernessTerrain. It worked before but there was a glitch on the map, I made it 514x513. I edited the map in GIMP to 513x513 and tried to open it but it still keeps closing it saying it has stopped working. It's very basic, it has a few rivers and hills and that's it. It's the fourth terrain I've made so far and the others worked fine. I tried remaking the terrain but I still keep getting that error.
