Hint list achievement
It’s a long-standing bug. Just keep trying, it took me over a year to complete all my hints. Mine was stuck on the Mail one, but eventually it completed. =)
Maybe when they release the new Tutorials, it will be easier to complete that Achievement.
I had the mail bug…well maybe call it the mail confusion. As for the other bugs…not so sure but I have found that many random glitches are resolved if you guest to another server. Some things do not seem to get fixed by logging out or closing down the game but resolve when swapping servers. Dunno…just a thought.
An update for anyone else struggling with this achievement: I got mine after just trying alot :p For the mesmer shatter I played till level 3 without shattering once, and then the tip came up. I played a ranger without using the pet functions untill level 3, and then when I went under water the hint came up. For pet charm, try to stand next to a juvenile pet for a while, log out and back in. The key to getting these hints to pop up is to be patient…veeery patient.
