📍 Description
Forward from SlimefunGuguProject/Slimefun#1058 and confirmed in the official version.
When copying a slime head in the inventory and placing it back into the inventory, there is a chance the item may disappear.
📑 Reproduction Steps
This issue affects all Slimefun heads. Using synthetic sapphire as an example:
Place a synthetic sapphire (PLAYER_WALL_HEAD) attached to the side of a block and aim the crosshair at it.
Open the inventory and middle-click to copy the synthetic sapphire in the inventory.
Observed Behaviors:
Case 1:
Original synthetic sapphire is in the non-hotbar slots.
Place the copied item into the non-hotbar slots.
