Oh I know what the issue is.
In InventoryPlayerController in the ServerLoadPlayerItems function you need to add another pin for the new equipment slot. It’s this function that is loading the Inventory Item into the wrong slot.
To get the load items logic to work with your changes it requires hooking up your new Equipment Slot and making sure it exists in the right place/order in the NPCItems struct.
Not sure why it thinks it’s the head slot on hover though, but lets see what happens once it’s loading the item into the right slot.
