“Vote too old to be changed”… but I haven’t voted!
I was in doubt whether to upvote or downvote this answer. I quickly undid both my up- and downvotes. But now that I'm sure I'd like to upvote, I cannot vote at all. The errror is:
Vote too old to be changed, unless this answer is edited (click on this box to dismiss)
But there is no vote registered for it, so how can the vote be too old?
