Your 'monsterhunter' mod adds world gen structures, but does not register them with the new MapGenStructureIO class. Its REQUIRED for anything that makes structures.

Ill try to register my structure soon. However i have a problem with NBT edit it says "empty string "

Thats because you haven't registered your structures!

Seriously, i'm not talking out of my ass, try it.
