Currently, the UI does not return any status indicator to the user when their transaction (transfer or purchase) fails. The database remains consistent, but there is no indication that the transfer failed and the user should try again. It would be much better if the UI after an interaction provided confirmation that the transaction was successful, or at least a warning if the transaction failed. Ideally this would be done in such a way that it's not annoying during the normal case that the transaction succeeds.
