Why does this not work?

I just found some of these on a moon that is part of the K'Rakoth mod. So that's one example

So... Where does one find this block? You'd think on the moons, where the rest of Erchius is found, but having entered a new solar system and landed on a previously undiscovered moon, I dug to its very bottom, down to bedrock, and could not find any. Not a single block. Only fluid and crystal ore. Is it really that rare?

is this compatible with Frackin' Universe?

i think it would be more fitting to smelt into crystal fuel instead

i dont know why no one else thought to make this, it seems so obvious. thank ya

OH god yes, thank you, I've been wanting something like this for a while now.
