I emailed them--I know it is just 1 point, but points are hard to come by on CR these days. This is the response I got (that came in at 2 something in the morning):
Thanks for your message. Members who did not receive proper credit have had trivia reset for them to re-answer the question this afternoon.
Not sure if that means this afternoon (4/2) it will be reset or if it happened yesterday & I missed it.
