In the dark energy generator interface, if you have a stack of ingots in your hotbar and try to shift-click them into the generator, it fills your inventory with duplicated ingots. Also, works in reverse - shift-clicking from your inventory, fills empty hotbar spaces.
Does not work with 1 ingot, but 2 becomes 3, 3 becomes 6, 6 becomes 21, etc. Seems to work with most stackable items.
