I got 27 reputation from this question Clicking "add / show xx more comment" doesn't focus on comment area (+25 for upvoted and +2 for accept). I have been shown a +27 notification in the top-bar and I have viewed it.
Again, I noticed a new +27 notification, I checked it and it just showed me the old notification. This has happened thrice after the original notification.
(I really don't know if this bug can be reproed but I just felt it would be good to report it).
