Xbox One Journey Mode item duplicating glitch

[MisterJRay]

So, I was just in a Journey Mode world with my brother, when he (on the left) discovered that items can be picked up in the inventory screen, then dragged over to the duplicate menu. When selecting "duplicate" while still holding that item, it will go towards the amount needed to duplicate that item, but it won't be destroyed as it should.

We tested this on a variety of items, and they all allowed us to perform the glitch.

This video demonstrates my brother doing the glitch. Again, he's on the left side of the screen.
