I know the issue is with the registering of the village, but I am not sure how to fix it as everything seems to be right to me.

Main class here and World package here

 

Does anybody know how I need to be registering this to get it working?

Was to tired last night, didn't think of adding "VillageBuildings.registerVillagePieces()" to my main class, which fixed it. Sorry for wasting your time!
