Okay so, I'm in a clan now and I've decided that I want to make my clan a map so we don't need to run around on the laggy Flourite Plains. However, the heightmap I've designed for the map, taken from the original WaterMill map terrain but with my own original design, crashes the game whenever I try to load it! The heightmap is titled Moonclanvalleyterrain.png and is located in my new map's folder along with the mask! Can somebody tell me if I've made a mistake somewhere? I'm pretty sure I followed the instructions of the map maker exactly!
