I just played a game (3156189) where I had the following weird thing happen:
So, at the start of my turn, I had 3 Archives that should have put cards into my hand. After selecting which ones, those cards did not show up in my hand, as you can see from the image.
The other weird thing here is the Sea Hag, which is a card I got from the Black Market, which means I only had one of them. Well, I distinctly remember trashing my only Sea Hag on the previous turn. I'm not sure if this is a Black Market bug, an Archive bug, or something else entirely.
