Ah, patch 0.19.10 might fix the issue, you can download it from the main link. You'll have to go back to a save prior to going into Beatrice's shop and handing in the quest though. I'll verify this fixes the issue by tomorrow, if you haven't tried it by then.
Edit: I still haven't managed to re-create this issue, but the users who were having this issue told me it's fixed for them.
