Windows 10 Edition does not send used items of CraftingPacket.
Affects any version since Windows 10 Edition is out.
On Pocket Edition the used items are sendt, and the slot positions in the crafting table/inventory, only the result.
The windows 10 edition sends an empty array. This way there is no way to detect wether oak or acacia wood was used to craft a sign as example. Effects every item/block that can be crafted out of different blocks.
Examples: Signs, chests, torches (which coal type), tnt (which sand type) etc.
