First I answered this question on March 30 (the same day as the question was posted). Later I got two upvotes.
Then a bounty was started on that question some time in mid-April. I received two upvotes during the bounty period (April 11 and April 14).
(I am not 100% sure, but I think both April 11 and April 14 fall within the bounty period; how can I check what period the bounty was on?)
My answer was never accepted. There was only one other answer that got only one upvote in total and was not accepted.
I was hoping to get half of the bounty following the bounty rules:
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 that criteria, the bounty is not awarded to anyone.
-- but that did not happen.
Question: What could be the reason I did not get (half of) the bounty?
