Guild Wars 2

After I finished the last hint which is finish your opponent in sPvP, the hint achievement didn’t jump out. After that, I checked my hints and achievement list, hint completion’s still 81/82 instead of 82/82.

I am experiencing the same issue. All 83 hints are showing as complete with check marks yet my Hint Completion under the Hero Achievement still says 80/82. I have sent in a bug report and screenshot, as well as searched the forums regarding the issue. I see many other players reporting similair issues but did not come across any responses from Anet on the matter.
