I encountered another instance of this bug. #6437249 on oregon, again, the game does not end when i use my last buy to end the game on a 3-pile and again, the last line in the log after reloading the page reads "Reshuffling the black market deck.".
So I am really convinced now that there's a bug where reshuffling the black market at the end of the game freezes it in a weird state. One thing I noticed though that seems strange is why is the black market reshuffled at the end of my turn and not directly after I played the black market that caused the reshuffle/directly before the black market that causes the shuffle? I'm not sure how that mechanism is supposed to work though.
I made a screenshot of the frozen state and also saved the whole log in case it's broken again, though only by copy+paste so it is really ugly formatted right now but that could be fixed.
