This question is, in my opinion, overly subjective, discussion-oriented, and potentially time-sensitive -- in short, a bad question for this site. I tried to vote to close it a while ago, but I was told that I couldn't do that because it had an open bounty.
Now that the bounty has been awarded, I went back and tried to vote it for closure again, but I'm now told that I already voted even though I don't see my vote in the close tally (as I write this, the close link says "close," indicating nobody voted to close it yet, instead of "close (n)" as I would expect if there were any votes recorded for it).
Note that at some point after I was told I can't vote to close questions with bounties, I also flagged the question, which may have something to do with the behavior I'm seeing.
Is this a bug?
