Infinity Backpack doesn't pick up items as expected, even when fueled
The problem is - Backpack has already have stone stored inside and mined stone gets to player's inventory instead of backpack's inventory

Translation: Auto-pickup is set to "Items only" mode
P.S. All slots have "Void excess" and "Restock" modes turned off

Can confirm the issue, tested every setting and the item just lands inside the inventory.

I have also been having this issue, have tried everything but the item still goes to the inventory instead of the backpack.
