If you run a Minecraft 1.7.10 server, allowing these dupes can completely ruin your economy. Here is how to patch them:

This is arguably the most consistent vanilla method for 1.7.10, relying on breaking the connection between the client and the server just as data is being written.

In Minecraft version 1.7.10, several classic duplication glitches remain functional because they exploit core game mechanics like chunk loading and entity transit that were not patched until much later updates. 1. Nether Portal & Minecart Method

More advanced servers may be vulnerable to "chunk rolling" using NBT-heavy items.

Power the piston with a fast or flick a lever rapidly.

Instead of vanilla Vanilla or Bukkit, admins use custom hybrid server jars like Thermos , Crucible , or Uranium . These jars are specifically coded to patch container exploits and multi-threaded inventory bugs unique to 1.7.10 modded.

Minecraft 1.7.10 handles chunk loading in a way that allows for item saving mismatches. If you can force a hopper to move an item at the exact moment a chunk unloads, the item can exist in both the hopper's new location and its old location simultaneously. How it Works:

The player loads the donkey's inventory with valuable items.

Would you like a more detailed explanation of how to instead?

Place the items you want to duplicate inside the donkey's chest. Step 2: Ride the donkey.

: If timed correctly, the item is removed by the player but also remains in the minecart that arrives on the other side. Critical Considerations Server Compatibility

Various glitches involving "breaking" full energy cells or storage drives while they were in transit (using teleportation or high-speed pipes) were frequent in early 1.7.10 builds.
