<p>I noticed a drop in my reputation today. Not that I mind, I have plenty, so I am asking why did it happen purely because maybe it is because of a bug. As far as I know reputation can get down because of the downvote, or because the person who chose the answer decided to choose another, or somebody decided to retract his or hers upvote. Although in the latter case there is some kind of lock after some period, so you cannot downvote if the answer did not change. My reputation dropped by 40 so this should amount to two reasigned answers and one retracted upvote. Not very likely for Sunday, hence the question. If this is a bug please retag.</p>
