The recent update, with the new season, has absolutely destroyed my decks, with cards I owned now being listed as uncrafted/unowned. I know something is wrong as not only are my decks broken, but also because some of these cards were given outright by the game when those expansions came out. Missing cards range from commons like Heart strike to legendaries like Patchwerk.
If this doesn’t get fixed, there is no point playing this game, as no one is going to tolerate cards they spend time and money on vanishing.
Beyond that, the quest pack from the last major questline never got delivered.
