Elven Chain Shirt is Display to reduce damage by 1 (meaning it does back in your hand before optional discards and reset your hand). However, if you still have damage remaining with no cards in your hand and the shirt displayed, you are force to discard the shirt.

I encountered this again recently. Definitely a dragging bug. HOWEVER, what appears to happen is that when you start to choose the card you are mending into (dragging from the discard pile), it seems like if you don't get it right on the first try, the card appears to disappear from the interface. This happened to me yesterday. I was able to complete the process by dragging the "invisible" card (which was on the right of the cards displayed from the discard) and brought it to my hand.

My guess is that you may have been using a weapon with a "if not proficient, add 4 to the difficulty of the check" clause with someone who isn't proficient with weapons initially (this happens to me EVERY TIME with Merisiel) Doh! I think you're exactly right. It happened again in The Poison Pill and I kept checking if there was a location that was causing it.

In Brigandoom, Jubrayl's card indicates a combat 10 check. However, when encountering him, it shows a difficulty of 14 (and a 14 is required). This was at the Farmhouse. Threw my off when I got a 10, but he did 4 damage to me and ran away.

I figure it's a dragging issue since I had trouble dragging Meri and Kyra into the party. Hopefully, I can do this on my tablet (knew I should've brought my tablet to work too).

I'm having the same issue. I cast Mending, chose to discard a Quarterstaff and was presented with a list of cards in my discard pile (Mace was highlighted). Can't do anything with the Mace. I exited the game and then continued and now it's showing "Exchange 1 card in your hand with 1 discarded card." The Quarterstaff is offset under my discard pile and the only cards presented are what's currently in my hand (no list of cards to choose from). This is on a Samsung Galaxy S4.
