UPDATE (2022-12-16)
Dear Community:
A small update from our end — we’re nearing the end of our investigation. While we’re still busy crunching some numbers, we believe we should now be able to provide adequate and commensurate compensation for those players who used a significant amount of valuable resources to clear stages on the original difficulty. It may take a little while for our servers to process everything, but you should receive something in your in-game inbox in a day or two at the very latest.
Our apologies once again for the inconvenience. Thank you for your patience and understanding!
