When crafting bone meal by the stack of bones, and you shift click with only two slots in your inventory, they are both filled to 64, but then only 21 bones are left in the crafting table. This means that when only two slots are open, one bone meal item is destroyed. It works out to be two stacks of 64, and one of 63, instead of 3 stacks of 64.
