We're always learning and improving when facing a Problem and in the 2nd Round we're having a problem that has nothing to do with our code, but it's directly related how the Blockchain works and the transaction fees.
Currently, we have a transaction that has a pending confirmation for more than 24 hours:
https://blockchain.info/tx/bd623d7023a90c7931b7059bd10230de4dd1fc84e7e21f08d067765a9b1ff6cd (Received Time 2016-05-15 08:58:15 ) and although there are other confirmed transaction after that the payouts are stuck until this transaction gets a confirmation.
We don't know if this transaction with low fee was intentional or just a player that has no notion how important the network fees are. Either way, we've already done a quick brainstorm on how to avoid this in the future and we have a solution to be implemented soon to take care of this kind of deposits and to maintain the game flow.
