Does the issue occur in the editor or during gameplay? If it occurs during gameplay, please specify which movement system is being used (free movement or grid movement):
The bug occurs during gameplay and is happening in both movement systems.
Briefly describe the issue you're experiencing:
On game start all descriptions of Items in Shop Item Slots are blank and when hovering over an Item in your Inventory with a description it will copy that description to all Items in Shop Item Slot's Description.
Are there any errors in the in-game debug console or external console window?
SCRIPT ERROR: refresh: Invalid operands 'String' and 'Nil' in operator '+'.
At: res://tooltip.gde:103
(This is appearing in the external console window every time I hover over a Shop Item Slot)
Provide the steps necessary to reproduce the issue:
Hover over Items in Shop Item Slot then hover over an Item in your inventory.
Provide a download link to the bare bones project (if applicable):
I will send it on Discord if needed.
