Duplication Bug

By using a piston facing the sky, a button on the side of the piston, and a chest on top of the piston players on controller can easily duplicate.

By hitting the button and opening the chest fast enough players can hit up on the d pad and press Y to take the item out of the chest, if this is done in sync with the piston beginning to lower the chest players can duplicate ANY item in the game.

However, if a player is a host of a world it is very difficult to do.
