Bug Report

Duplication glitch where you use Ender/Dark steel armour with the Dark Steel Upgrade "Inventory" to duplicate any item at all by taking on and off the armour piece.

Expected Behaviour

When the armor piece is taken off it should keep the stored item and should be right-clicked to place back on whatever armor slot it belongs on, but instead of keeping the item inside the armor, when you right click the piece it gets back on the slot it belongs and keeps the items and upgrades BUT also duplicates all the applied upgrades and stored items and put them in your inventory (or on the ground if inventory is full)

Possible Solution

Remove the recipes for the inventory dark steel upgrades until fixed (if you can't just immediately fix it)

Steps to Reproduce (for bugs)

1. Make Dark steel or Ender armor and apply the inventory dark steel upgrade
2. Set a keybind for the inventory
3. Open the inventory and put in whatever you want to duplicate (diamonds, for example)
4. Take off the armor and put it back on by right-clicking the piece in the hotbar
