I've been searching the CS for a Gemstone Setting recipe for days. I assumed they had made it a drop from mini boss since I could no longer craft it. But, I did wonder if it was a bug. I've also been searching the forums for similar problems. You are the first I have found. I guess everyone is playing the new maps? I think I'll go post a new thread in the Bugs and Technical Issues thread and see if I get a response. Is it a bug or a rare recipe?
