The best way to address it would be to go to her profile and find the quiz. You can quickly play it again and submit a correction from there. Since there are multiple quizzes used for each day's Brain Twist, and it is possible that more than one came from the same author, that would be a definitive way of identifying the question that needs to be corrected. And it works whether or not the quiz author is still active on the site.
