I've been stumped by this for a while now, as I'm not particularly good with worldgen, but it's never been an issue before. However, I'm updating one of my mods and I'd hoped to have a few ores found out in space; y'know, asteroids and such places. Unfortunately, I can't seem to add any ores to the asteroid biome and I can't figure out what's the big difference between it and other biomes which prevents this. Any worldgen masters out there who can help me figure out what I'm doing wrong?
