bug with shift-click crafting?

[psychoseby]

I made 2 sets of 8 nails and strips, put 4 of those nails and strips in the my crafting box to make some chests, and divided a stack of 64 boards evenly into the crafting box (8 in each slot), hit shift and crafted.

It output 8 chests,  used all my planks and i still have 12 nails and strips leftover

forgot to specify my planks were all used up in the process

Shift-Click crafting is currently whacky and error-prone, so I'd assume something like this just goes on the pile aswell.
