Wicked Eyes and Wicked Hearts Fight Bug

Hi there, the dragon age twitter account told me to post my issue here. So I played through this mission during the weekend, luckily saving it earlier on during it. When I got to the fight with Florianne, after many attempts, i finally defeated her. I looted her body and received XP, but the game did not seem to register she was dead, her body disappeared so i am now stuck in the courtyard being told to confront Florianne but i can't. I'm not overly enthusiastic about replaying the whole mission again, so any assistance in this matter would be hugely appreciated.
