I opened my DH14 only to find out ALLL my progress has been reset! I was on Level 79 with 10 million Hunter bucks, almost 500 Gold credits, all Regions completed besides the New Sleigh Event. All my purchased weapons are gone as well! I've rebooted, deleted the GLU WALLET but still nothing!!!! This is jus crazy
What device? If IOS try reinstalling from your cloud. It worked for me. All you lose is anything after your latest cloud backup.
Sorry I'm no help.
