I am not sure what is happening... when I get to the Qi numbers I can't get more than 13Qi... it will go up to maybe 25 Qi but then drops back down to 12 or 13 Qi. leaving me un able to get to the next upgrades.
thanks for reporting this! its sounds like a bug with the currency display or calculation when reaching higher values. i'm looking into it right now and will deploy a fix as soon as possible!
