After threatening or saving the slave in the mines for information, I travelled to Isla Muella and searched every house for someone who knew about the rocks. (I don't care what they are called. Rocks, slates, stones.... whatever you had to find in the mines) I couldn't find anyone, so i looked in a walk-through and found i had to go to the tavern and talk to the tavern-keeper (Tavern-keeper, inn-keeper.... whatever. ) about Danielle.
So I fast-travelled to the tavern, and talked to the man at the counter about ' business ', but there was no option to talk about Danielle. Have I done something wrong? Or am I looking in the wrong places?...
