A bounty was put on this question by Alix Axel about eight days ago; for which the seven day period as well as the grace period has now ended. There is no indication of bounty being awarded to any of the answers. Looking in helpcentre regarding bounties it says;
How is a bounty awarded?
The bounty period lasts 7 days. Bounties must have a minimum duration of at least 1 day. After the bounty ends, there is a grace period of 24 hours to manually award the bounty. Simply click the bounty award icon next to each answer to permanently award your bounty to the answerer. (You cannot award a bounty to your own answer.)
If you do not award your bounty within 7 days (plus the grace period), the highest voted answer created after the bounty started with at least 2 upvotes will be awarded half the bounty amount. If there's no answer meeting those criteria, the bounty is not awarded to anyone.
If the bounty was started by the question owner, and the question owner accepts an answer during the bounty period, and the bounty expires without an explicit award – we assume the bounty owner liked the answer they accepted and award it the full bounty amount at the time of bounty expiration.
As a special bonus, any reputation you earn from being awarded a bounty is exempt from the daily reputation cap.
