I went to the Guild Master in Sargoth and asked to buy land to operate a productive enterprise. When I selected that option, the reply was, "Well, Michael, you already operate a Lady Afrid here. There probably aren't enough skilled tradesmen to start a second enterprise." Then when I try to click the dialogue screen to dismiss it, it doesn't work. I can still access the notes and such by clicking on the guildmaster's portrait, but can't actually leave the dialogue.
