About a year ago, the count of votes cast was changed so that it includes votes cast on closed questions. Prior to that, your vote count would go down when a question was closed.
Every now and then I'll notice that my total vote count has gone down and I'm trying to figure out why. I'm guessing migrations, but I can't find anything that says one way or another if your vote count goes down when questions are migrated, and I can't think of any other situation when you'd "lose" votes.
Are there any (other) situations in which a person's vote count would go down?
