Using a Samsung Galaxy Tab S
Also am playing on version 0.13.1 alpha which this form says doesn't exist

I have a whole stack of vines and a whole stack of stone bricks. I click to create the mossy stone bricks on the crafting table or my inventory crafting. I click all 64 times. All of the vines get used up, but only one of the stone bricks gets used up and I only have one Mossy Stone Brick.
