The item updater dupes armor
Summary
If a player is wearing armor that has been updated using the item updater, the armor will be duped when they join the server.
Steps to reproduce
Here's an item to reproduce this issue: https://pastebin.com/y3WUfTEU
Equip this item in an armor slot. Now update the item to this: https://pastebin.com/8wA1mmK3 reload mm leave and rejoin the server and the item will be duped when updating.
Current behavior
The item will be duped perhaps even multiple times. The original item which is still equipped won't be updated.
Intended correct behavior
The equipped item should be updated with the new lore and not be duped.
Server log file
(I messed up the armor config on the first try so ignore the yaml error sorry)
Debug log snippet
I think the above file has this.
