Saw some threads regarding this, but all from years ago, none since the new rollout, so here's a new thread. Checking out my profile, I saw that I had a downvoted post! Me! After crying for a few minutes, I click on the red "thumb down" icon to see which post was voted down so I could grovel in that thread and hope someone would take pity and upvote me so I was batting 1000 again. When I click the icon , I get a screen with the title "Oops!" and the text on the screen tells me "There are currently no results. Try again later". Obviously I was offended by the "Try again later" part, as if the website was just assuming I'd get more down votes, but such is life.
Anyway, screenshot is attached. There is either a bug that says I have a downvoted post when I don't or I have a downvoted post, but the database query didn't find it.
