Play tested with git update 1812d7d2bc043869d5e1a68b8506467c33e28643
Dialog error was not encountered. The interface/triggers to move the
quest/dialog threads along are still "clunky". Tux has to be at the "right" spot
almost walking out of west gate before Pendragon says "some one has been waiting
to speak with you" - which moves the quest to completion. However, the game is
playable.

+1 for closing bug.
