I'm not sure if the Mayor is having a private moment somewhere, but he has vanished from the Inn (of course coinciding with the appearance of the shade) and does not come back when the shade is gone. I'd really like to turn in a couple of quests but it's a bit difficult. Is he sleeping off his bender somewhere in the slums? I've waited through several cycles of the shade's appearance but ol' Auggy isn't coming back.
Using Mac with OSX and version 1.1.1, though my saved games are from 1.0.3. This issue has happened with two sets of saved games.
