At Why are some singular masculine attributive adjectives treated like that?, I started a bounty with a notice saying "authorative reference needed". However, while the bounty is still active, the notice was removed by one of the users who answered the question. I cannot understand why the bounty notice should be removed while the bounty is active.
I removed the notice because the text was ... extremely confusing. Not the "authorative reference needed" (which is still visible in the timeline); the custom text you wrote in the box. It didn't seem to have something to do with the question at all. Maybe with another one of your questions; I don't remember anymore, and there's no way for me to check or undelete the notice. Moderators can only remove the entire notice, not just the custom text (otherwise I would've done that instead).
Your bounty is still active and the question is still featured. The fact that I answered your question doesn't play a role; in fact, I do remember that I only noticed that after removing the bounty notice.
