We have updated Avadon 2: The Corruption to v1.0.1 on our site for Macintosh and Windows. This update fixes a number of issues, including a weird bug that could make a major NPC disappear. We will update the versions on Steam, GOG.com, etc very soon. If you get Avadon 2 from our site, just download the v1.0.1 demo and install it over v1.0. This will fix the problems and not affect your registration/saved games.
