Duplication glitches

Dupe glitches are glitches that allow the player to duplicate any item they desire. There have been several dupe glitches throughout the history of 2b2t. While this is technically illegal on the server due to the rule against game-breaking exploits, Hause allows the players to keep the duplicated items, and doesn't hurry when it comes to patching them (save for the 1.12 Crafting Dupe which destroyed the economy in mutes, which was resolved within hours.)

Known Dupe Glitches
Note: All minecart duplication glitches (which are all patched) mentioned here are all different versions of each other with slight differences in their usage.
 * 1.12.2+
 * January 2020
 * Restart Dupe
 * Unknown, possibly jakethasnake52
 * When the server restarts, chests do not update at 4 seconds. Get all the items you want to dupe into a chest, and quickly take them all from the chest at 4 seconds. After the server restarts, the items will be in your chest and inventory.

Other Lesser Known/Extra Dupes
The Ender Chest dupe was a public (yet) but still a bit secret dupe as people thought it was fake, It was active in 1.10, 1.10.2, 1.11, 1.11.2 and 1.12. Its now patched by either hausemaster or PaperSpigot, it worked like this:
 * Open an ender chest, look at the GOLD plate on it
 * Drop an item while in the ender chest / or pick it up at the same tick you open it
 * Dropping the item while in the ender chest will eventually cause it to duplicate once.

'''AKA. SLOW DUPE. '''(It could take many hours to dupe the item just once)

The Zombie dupe might seem like the Donkey and Llama dupe from 1.11.2.

To do it: (maybe this isn't 100% accurate)
 * Make a Zombie (Regular) wear any type of armor and push it through an End Portal (might work with nether )
 * Make it a HALF HEART before you push it in, make it take damage at the EXACT same tick it goes through the portal.
 * If you are lucky, it will duplicate.
