I'm running All The Mods 3, and in this pack when attempting to quarry Rock Crystal Ore from Astral Sorcery. it just vanishes. Let me know any other info you need. I tried clearing and non-clearing versions of normal, silk, and fortune. Same result.

Not a bug in the builder. Some blocks dumply cannot be quarried

Fair enough! I'll set mine to clear and stop at like Y=3
