OK, I know bounty issues are trivial in the big scheme of things, but having a bounty taken away by the OP after awarding it is really making me upset. (Maybe I should cut down on the caffeine?)
I've been getting irritated enough by bounties expiring without being awarded despite the fact that I gave a complete answer (questions with low views and no upvotes and the OP disappears). Losing bounties after they are awarded takes this to a whole new level of frustration.
I was awarded a bounty for answering a question. Then I lost the bounty when the question was deleted ("voluntarily removed by its author"). I have no idea why the OP deleted the question, although I suspect it was simply because he was asking if something was possible and got the answer "no".
It is bad enough that all the work I put into answering the question is lost to the rest of the world because the OP deleted it, but to lose the bounty as well feels like a ripoff. I see absolutely no policy reason for taking back a bounty that was properly awarded.
Please change the policy so that bounties that have been awarded are not taken back when the question is deleted.
