When building Lonsdaleite items in a crafting table, every single recipe is grouped into a single entry, making it very difficult to find exactly what it is you're looking for. Might I suggest removing "group": "lonsdaleite" from your recipe JSON files so that these items appear as separate entries?

Ahh. Apologies about that. I made the change and am pushing another update tonight.

Still learning on this end, but trying to dive right in. That is a remnant from an early test.

Thanks!
