STONEBRIDGE CITY BUG in Dungeon Siege III: Technical Support (Spoiler Warning!) Posted January 26, 2015 Hi. I was playing (Dungeon Siege 3) on my PC and I came upon a glitch or bug or whatever you call it. I was on the city of Stonebridge and I was looking for “The Grand Chapterhouse”. The city map ended unexpectedly and there is no more graphics. Everything is gone and you can see only clouds. I have included a photo of the problem. Please help me.
