I've answered a question, External links URL encoding leads to '%3F' and '%3D' on Nginx server, within a couple of hours after a bounty was started, addressing concerns of both the OP and the person who's running a bounty (who requested official sources — "Looking for an answer drawing from credible and/or official sources.", a request with which I've complied, by including the original answer for a similar question by an developer of the technology at stake).
However, it would seem like bounty rules prevent awards within 24 hours after the bounty was started. Is that why the bounty was not awarded originally?
Else, there is only a couple of hours left until the expiration of the grace period; is there a way to nudge the person who has offered the bounty to award it, because all matters of the question were addressed?
