I've completed my Forgotten Sanctum business and now I can't leave. Enjoy the dataz.

Update: I also crash when simply exiting to the main menu from that point, so I don't believe the issue is with loading the world map.

Hello Fireballs,

 

I'm sorry you are getting these crashes during your playthrough.  i took all the amazing information you provided, put it into a bug report, and assigned it to the Programming team for an investigation.  Also, thank you for letting us know you are getting a crash when exiting to Main Menu, otherwise I was thinking it was another transition issue that we have seen before.  If you discover anything else about this, please continue to post it here as I linked this thread in the report to be used as a reference.

 

Thanks again and sorry for the inconvenience this is causing.

Happened to me, too-- crashes both on leaving the Hall and on exiting to Main Menu from a save in there. 

 

In case another save would help:

Update:  The Steam "Verify Integrity of Game Files" button worked.  The world map took a suspiciously long time to load, but I was able to walk out of the Hall.
