So, I opened Watermill so I could make a map with it. I erased it, yes. But the issue is when I went to save it, it was .xcf. Im pretty sure its supposed to be .png, right? I dont know how to switch it over to that, but I dont think Im supposed to ask how on this forum. I use Gimp, and when I make a map and its most likely not .png, I think its the whole reason the game crashes when I try to put the terrain on it. Do I just type .png at the end or do I have to do something else? Is it supposed to be .xcf?
