Free Epic Chest

[Rotan]

Maybe Its the game giving me back chests I lost but if I trigger every chest quest the game gives me an extra epic chest (I get it before claiming) If I have no chests before hand and open it before the claims I get the item (for keeps I counted) otherwise if I dont open it, the chest goes poof and goes away

edit: I might try and upload a video of it tonight. Curious if its just my game
