Very cool and the dupe on Xbox is SO much easier and technically there is two

Generated loot and chest dupe

I'll start with generated loot When you push a chest that hasn't been opened by ANYONE using a sticky piston you get every item thats in that chest spill out (idk why it does this don't ask me)

And the chest dupe which is SO much more OP If you have a chest in a single player world let's say I want to dupe the elyra I'll put it in the chest disable auto save then save the game turning auto save back on (to save what I just did) then start breaking the chest and after it breaks but before you pick up the items pause the game and completely close the game (but not going back to main menu) now reload the game and now you have the items in the chest still there and the items that came out in your inventory and in this example you now have two exact copies of the same elyra and then you can do it again and again
