Recursion causes items to duplicate on client, then disappear altogether.

When recursion is anything above 0, and you have an item with a reversible recipe (e.g. iron ingots into blocks and vice versa), shift clicking on of those recipes doesn't always work properly, and creates ghost items on the client, which disappear when you click them or leave the GUI. Sometimes however the original items also disappear, despite being real.
