Had 4 citadel chests [3 + daily 1]. Opened one. Opened the second, flash crashed. Reopened the game, not only can I not access the second chest or find the rare boots that were in it in my inventory [so presumably the other items as well], but I'm down to -1- chest left to open. Weird quirk :X I may have to review my 'Card Hunter always saves your progress' statements I make to new players ;P
