I got the short bow +1, an epic armor, and staff +1 from the tutorial. I equipped them in the deck once I started a new game. Now they don't show in the deck, but the items I put in the stash that they replaced are still in the stash. Also the collection shows I own the cards. What happened to them?

... what is in your deck instead of those cards. (What cards did replase those rewards?)

the same thing happend to me.. i had a shortbow + 1 and a flaming short bow +1 after replacing them for a dagger and a dart both bows were gone.. after i looked again i had 2 copies of a dagger and a dart.. one of each in the deck and one in the stash..
