In #25286755 on oregon between turns 13 and 14 my Merchant Guild just wasn't there - I had my whole deck in my hand eventually, and it was neither there nor in the trash nor of course played cards, so I bought another one. The opponent was as astonished as I was that I couldn't play the first one.
After finishing the game (next turn) both showed up in the summary.
