Item stacking bug in match

Certain items stack incorrectly in a match if the rotations are different and quick transfer is used.
I managed to reproduce this with:

• birch logs

• oak heartwood

• wood saws

• broken greatswords

My theory is that every 3 wide / long item is affected that can stack.

This issue only seems to appear if the character does not have access to all 8 quick slots. (4 class + 4 generic toolbelt) (thanks Wizup)

The backpack does not have to be empty (other than stacking item) for this bug to happen, but it reduced the possible variables.

The item in the backpack does not have to be in the top left, it can be in the middle of the backpack.

This can result in item loss depending on the rotations (clip 1 would correct the stack after extracting, clip 4 is item loss)
