Item Duplication Exploit

For almost a year this glitch has been in the game, It allows you to duplicate items you have, in order to do it you need a sticky piston, some redstone, a chest and good timing. How to do is that you to have a sticky piston to push a chest with the item you want to duplicate and the second the piston is about to retract you need to “quick move“ the item in the chest into your inventory and if done correctly they should be in your inventory and in the chest if you were quick enough it does take a couple of tries to get used and it’s really simple so if you can please patch this glitch as soon as possible, Thank You.
