Working On ThisPossible bug
So I was on the comments page for a circle I'm subscribed to. Sometimes when I upvoted a comment, the ticker increased. Other times it stayed the same. It was completely random. And it was an older post so it was not like my vote was being cancelled by someone else voting at the same time.
I tried an experiment, too--on a comment where I upvoted and the ticker did not increase, I clicked again to withdraw my upvote, and the ticker did decrease. So on a comment that had 3 before I did anything, I upvoted and it stayed 3, but when I withdrew my upvote, it became 2.
I think there's some bug that has been introduced.
