Prevent Item Duplication When Sharing Shulker Boxes

Why Duplication Happens

When players open shulker boxes directly from inventory without this plugin, items can be duplicated if the server crashes or if multiple players access the same box simultaneously. The plugin prevents this by saving all box contents to a server database instead of relying on item data.

How to Stay Safe

1. Always open your shulker box through your inventory—never place it on the ground to open it

2.

3. Close the inventory screen completely after transferring items; this triggers the save to the database

4. If you're on a multiplayer server, avoid having multiple players open the same shulker box at the same time

5. Trust that the database save is automatic—you don't need to do anything extra

If You're a Server Admin

Run /axshulkers clear on a shulker box before giving it to players if you want to reset its stored data and prevent any duplication exploits from previous sessions.
