I've come across two combinations given by quests that I can't get to work for me. The first is 1 Iron Ingot X 1 Alkahest to give Ninja Stars, the second is 3 sapphire shards X 1 Alkahest to give a Sapphire Globe.

Both of these combinations are spelled out in the quests, I've tried them with the ingredient orders switched, all the walkthroughs I've looked at seem to indicate that I'm doing the right thing.

Has anyone else had problems with this? Is there some other condition to crafting I overlooked?
