I didn't took chance i got 2 days without internet, and trust me not by choice. And Still i was 11 out of 12 and i did launch the quest. So no, there is no question as to not get the girl since the quest was completed.
I am quite normal and the text says that you get the girl if you complete at least 12 quests. A thing i have done.
Since you are not from the team i will wait now for a true and official answer to that issue, if any. I am not very pleased as of now.
