Don't know if this is overworld-only, but I doubt it. It did grow at Y=230 on the same map.

Probaly the same thing as no ores below y0

Ores below y=0 do generate in CustomCubic world type.

I simply didn't remove height limit from chorus.

If there are generating on custom cubic why it does not generate on vanillacubic? Isn't it just a copy paste code?

VanillaCubic isn't even coypasted. I just directly use vanilla generator, which obviously only knows about 0-256, and fill everything below with stone.

Closing as this is part of #152
