After an evening of playing the game and already having experienced some power outages my power went out again but this time my character i was playing on during the power outage got fully wiped, this Hero had about 200 levels and a whole bunch of unique collectibles.
after the outage when i restarted the game i had to reconfigure the hotkeys and had to do the first steps you do when you get the game and open it up for the first time (brightness test, etc...).
in the pictures you can see a screenshot of my lost hero's inventory and my heroes selection screen.
Please if it is possible i'd like to get my account and its data back.
