Have an issue today were my save wouldn't load, so i loaded a previous auto save and tried going back to the area only to get hit with a transition error then found this in the error log:
Game Version: 1.1.5.12

Clearly there is something funky going on Zamans lair in my game and reinstalling it did nothing.
