After you get initially captured in the Mountains of Freedom, the Automaton will never leave his office, putting the dungeon, and therefore the game, into an unsolvable state. The Automaton is supposed to leave his office periodically, and will approach the door time and again, but will not open it.
It would be nice if, after fixing/circumventing this bug, you sent a save of just after the automaton opens the door so I can solve the dungeon and continue the game. My email is email@example.com.
Attached is a saved game directly prior to sleeping with Frigidazzi.
