I was literally about to go make this exact mod so I could play bob's mods without biters. Thanks for saving me the trouble!

My concern, however, is with the recipes compared to the rarity of the various gems. I know you were matching the colors as much as possible, but the problem with that is that the 6 colors of alien artifacts are more valuable based on a tiered system. Orange/Blue for MK 3 armor, Yellow/Purple for MK 4 armor, and Green/Red for MK 5 armor. I know it seems counterintutive to use, for instance, rubies to make orange packs/artifacts or emeralds to make yellow ones. And maybe it's not worth worrying about. But it's something that bothered me.

I've actually taken to changing the payout of the various gems to all be even in bobsmodsconfig, because I'm sick of having infinite amounts of rubies stopping up my diamond production.

Anyway, like I said, great mod!
