Is anyone able to get this working with 1.12 worlds? I'm desperately trying to generate ores and stone variants in a vanilla minecraft map, but keep receiving "Error: Failed to open world" with "Exception: Object reference not set to an instance of an object."
If the NBToolkit party is officially over, can anyone suggest a way to generate ores in existing 1.12 worlds without deleting chunks?
