Keera

Hello! I took a long break from playing pillars of eternity. Now that I started again I wanted to complete built to last, but as I went to the Abandoned House where Vianna is supposed to be hold hostage it was empty. I don't remember if I already went there or not, but if I did I should have received Vianna's research which I haven't. I really want to do this quest since I plan on joining the crucible knights. Can you help me? Is there a way to restart the quest? (I have done lots of quest since I started it so I'd rather not go back and search for a save where it's not started.)
