I just clicked to vote this question up, but the number decreased to zero instead. When I tried to vote it up a second time, it said my vote was too old to be changed.
Has anyone else run into this?
Prior to yesterday, I had never cast any vote on the question one way or another nor attempted to do so. When I visited the question yesterday, it had a "score" of +1. I attempted to upvote the question by clicking on the up arrow. When I did this, the score reduced to zero. Then I clicked it a second time and it gave the "Vote too old to be changed" error.
In fact if I go there right now, the score is zero and if I click the up or down arrow it gives the "too old to be changed" error. This would imply that I've voted, yet some folks with the reputation to see the individual up/down votes are saying that the question indicates that it's received no votes at all (up or down).
Furthermore, poor Joe Casadonte (author of the question) now has a -50 reputation associated with that question (if you go look at his reputation tab).
Lastly, I happened to have another browser window opened to the same question prior to this incident. When it happened, I saw his rep score go down. I would have though I was seeing things had I not had the other window still open with the higher rep score.
