So, there's a uu-matter recipe for plutonium that inolves crafting a uranium cell with UUM. The recipe is enabled in the IC2 Config file both on the server of FTB Ultimate and the client. When I place the recipe on the crafting grid, the plutonium rod then appears in the craft product box. But, when I try to actually craft it, it briefly appears in my inventory, and then disappears, with my uu-matter and uranium returned to the crafting grid. It seems to me that this is a server problem, because of how it's showing up for a split second as crafted until the server overrides it - but the recipe is enabled on the server, as I said. I had the same problem in Beta A, too. Has anyone else experienced this issue and found a fix for it?
