Is the map upside down? I downloaded it, the geography checks out but the soil is not made with dirt and snow and stuff, it's weird blocks like wool and terracotta, the surface is not smooth there are holes everywhere and the world is not very deep so you can't go mining, it's not suitable for survival or running a server on.

forgot to add that I'm still working on it so if there are any problems with texture/ terrain info I plan on fixing them
