Larian Studios Forums Divinity - Original Sin Divinity - Original Sin - Technical Issues Game crashes in Luculla mines

After setting off the detonator and blowing up the troll prisoners there's a dialogue option between the two main characters inside the cell. When activated the dialogue option says nothing, the portrait of the initiator of the speech is empty with a question mark in it, and the only option for a reply is "end." If you click "end," the game crashes.
