@DiDA Confirmed, I'm also getting the “error - invalid wallet earned” as well.
What I'm currently doing right now as a workaround / temporary fix for version 1.9.3:
I have the original game installed and the modified iOSGods version installed as well (Please look at tutorial that @DiDA posted called "How to Install Hacked IPA as a Duplicate App & Keep the Original!" Make sure for both versions to have your Facebook linked. Open the iOSGods version up first and start a mission (until your energy bar fills up to 100 and gold coins reach max value). As soon as you see this happen, close out of the game and open up the original version. You should start exactly where you left off but the energy / gold coins should be max value. Side note: you need to do this every time when you run out of energy but like I said this is only a workaround / temporary fix till @DiDA is able to address this issue.
