The Timing Cycle: This mod will attempt to dupe every 100 ticks (5 seconds) based off the time of the world. It is done this way to avoid requiring the mod to communicate with other instances of itself. Both users must click the dupe button within that 100 tick timing window for the dupe to work. Due to how this timing system works, best results come from running both clients on the same network.
Container Detection: Internally, every “chest like” container in the game is the same menu (except shulker boxes). Because of this, the mod detects whether a container is a chest boat by simply reading the name of the container (the mod still supports language differences if you change the language of your game). This can have some side effects, like showing the dupe buttons for containers renamed to “Chest with Boat” (or any language equivalent if you’re running the game in that language) even if the container isn’t a chest boat.
Chest Boat Detection: The way this mod determines whether to show the menu to disconnect from the game or show the menu to move the items to your inventory is based solely off of whether you are sitting in a chest boat. Not specifically if the menu is the chest boat you’re sitting in, but rather if you are sitting in any chest boat at all.

This dupe also requires a second person. Unlike the previous dupe, however, it will require a second person instead of an alternate account.
The first player must enter the chest boat and get ready to quit Minecraft. The second person needs to enter the chest interface and begin rapidly placing and removing the chest.
Then the boat player needs to exit Minecraft. This will sometimes result in duplicating the item, ending up in the chest and the playerâ€™s inventory.
