Hint Completion Achievement
Stuck at 80/83 myself…
A lot of people seem to be having this problem. There are several threads about it. Mine was stuck at 79/83 when I had only 3 left, once I got the 1st of 3, it jumped to 81/83, then it stuck there until I got the very last and it completed 83/83. Odd numbers only lol. It’s helped some to try a new char and redo a few (mailbox, pvp treb, WvW, etc), most it hasn’t helped so much so much.
Hopefully a dev can get it on this for you guys.
