Huh? I always rejected her and do Abbadon’s ‘Traditions’ quest.
So, I don’t know why, but maybe, as the header of your comment suggest it, it was just a bug introduced in the version you mentioned (0.7.11).
Edit:
Wait… Now that I re-read your comment, I am not sure of whom you are talking about since there are no bunny girl as far as I know during the quest ‘The premier’. At first, I thought you was talking about Alba during the introduction, but it’s not bunny girl either.
Plus, ‘The premier’ is pretty straight forward, I made a new run trying each of its outcome and the ‘Traditions’ quest was still there for me to go trough.
