1) have max (or close to it) smelting.
2) put more than half a stack of an ore in a furnace and wait for it to smelt.
3) have your inv full except for one items worth of whatever the furnace product is. (so like a stack of 63 iron and the rest of your inv is full).
4) shift click on the furnace output to remove only one item-- leaving 63.
5) let one more item smelt so the furnace appears to have 64
6) manually drag (don't shift click) the stack of product out of the furnace- it'll be 65 items
when you drop that and pick it up with only one free space in your inv, it'll look like there's more than one left on the ground, but for me, there was only one, and the "dupe" was visual only-- idk about VK's player.
