Is it a bug or is it on purpose and just very annoying, that when I try to find swappers of a certain banknote issuer, it almost always changes to coin exchange? I understand that might no-one wants to exchange banknotes from those issuers yet, but then it should show "There's nothing for exchange" and not navigating to coins.
Just checked that it's definitely a bug, because when I changed from something to Austria, it again gave me the coins, and previously I had found exchangeable Austrian banknotes.
