Does the issue occur in the editor or during gameplay?
If it's a gameplay issue, please specify which movement system and camera type you're using (free movement vs. grid movement, third-person vs. first-person) or N/A if not applicable:
Briefly describe the issue you're experiencing:
When using a custom assigned inventory, items are not going into the inventory when using give_item.
No icon shows of the item flying towrds the player, the inventory when open is empty, and the below error shows on the terminal.
Are there any errors in the in-game debug console or external console window?

Provide the steps necessary to reproduce the issue:
- Start the game with a custom inventory and an item to collect
- use give_item() to give yourself the item
- witness the eror and empty inventory.
Provide a download link to the bare bones project (strongly recommended if it's an in-game issue, since this helps significantly when attempting to reproduce it; the report will also be given more priority in this case):
will provide once i've zipped it up.
