just played a game between OneBlood and Doctor Futurity at about 12:15 est on 2/24/17. Tried to play inn tunnel combo. i could discard the tunnel and the game stopped for me to reveal tunnel, but i couldn't do anything except skip it. I'm thinking I can't reveal from trash when i discard more than one? Dunno if this is a known bug or something I did wrong. Thanks for looking into it, assuming someone does.
The buttons to activate tunnels appear below the log atm.
