Guild Wars 2

I recently got my last hint, but the acheivement still says 82/83. I looked in my hint menu thing and I have checkmarks for all of the sections.

One possibility is that you need to re-achieve the “too many mail items” hint. Delete your discretionary mail (from BLTC and other players) and then have someone send you 11-15 email quickly — when you have about 8-9, start deleting.

I don’t know if that will work for you, but it reportedly worked for 2-3 people I’ve seen post about this.
