Shulker boxes can be used to clone mass amounts of items

 If you use a shulker box, you can clone any amount of items inside. This can happen either on a multiplayer game or single player.

to activate it:

1.place any kind or amount of items you want cloned in shulker box

2.break the shulker box with a pickaxe (so it drops) and place it down at the same time you pick it up.

You should have two of the same shulker boxes (one in your hand and one placed) but if you try placing the one your holding again, it will disappear.

3.to complete the process, color the shulker box your holding with any dye and you will have the same shulker box with the same items that can be placed and repeat ably cloned but a different color.

i would love to see this big fixed because it has caused me and my friends some trust issues in our world. Thank you.
