i am doing the Branches of Darkmeyer quest and i got to the point where you attack Vanescula, when she knocked me back she kept attacking me. she only hit 0's and 1's but this prevented me from talking to her and logging out. the way to get arround this is to trap her behind a door. see picture. also if you do logg out she will remain in the same place as you left her. hope this will be useful
