Realizing that I'm running the risk of sounding extremely petty, I'm confused and curious enough that I have to ask. :) There was a question with a bounty of 50. I answered this question after the bounty was placed, and my answer had two upvotes and was the highest ranked answer at the time the bounty ended.
It was my understanding that in this situation, having met the criteria in the last bullet point about bounties, my answer would have automatically been awarded half of the bounty, as no other answer was chosen. Since this didn't happen, I obviously seem to be missing something, and I'd like to understand more about how bounties work.
