When first equipping a fresh Fin BP (don't think it happens if you switch a bound one to a different character) as you pick things up items will go to the Fin BP for about 30 stones then immediately spill over into your inventory. It will only hold MAYBE 1/10th of what it should, until you log out and then back in which causes it to work properly.
Not game breaking by any means, just reporting an issue.
Thanks :)
