So i've been trying to create a new world with custom biomes and structures. I've switched back and forth between the beta build and the 7.2 version or whatever it is. There's nothing wrong with the biome I made or my structures. I've checked them all and i've had them load a few times but parts of the world end up with chunk errors because of how I got it to work. I was just curious if someone had a good way of getting a world to load with custom biomes/structures and what not. I've edited all the ores in all of the biomes possible and created my own biome with structures and added structures to other biomes. Anything would be helpful.
