I have been there before at this point in the game. Previously I was sent there without realising what was happening, and it worked fine, but I then reloaded a previous save, because I was intending to do the ToSC stuff before that.
Since I have completed the ToSC missions I'm getting this crash, and it's affecting all my saves - I also cannot go to candlekeep with much earlier saves.
I have been using the widescreen mod, and previously had trouble with some buildings (such as jovial juggler, or helm and cloak) but I could usually access these by either reinstalling the mod with a different resolution, or uninstalling it all together. Neither of these methods work to get me in to Candlekeep however.
The crash i'm experiencing is not a normal crash to desktop with an error message. The game screen freezes and goes black, and shrinks to a chunk of my screen the same size as the games resolution.
Any help would me much appreciated. I was really enjoying this game!
