I could swear there was a 500 point bounty on this question: How to fix Bang and Olufsen Audio for HP laptops?
...and I could swear I saw it go into a 9 hour grace period last night. But upon looking at it tonight I don't see the slightest hint there was ever a bounty on the question.
Which begs the question could the bounty have been redacted with some sort of magic wand? To the best of my knowledge once a bounty is pledged the sponsor looses the points and it is awarded to the accepted answer and lacking that 50% is awarded to the answer with the most upvotes.
Can a bounty simply disappear?
