Achievements not completing?
You have to get the achieves on a character that has done the story section. So if you did it on your guardian then the guardian is the one that does the achieves. If you want to get achieves on your warrior, you will need to do the story first with him.
ANet may give it to you.
Kind of stinks it’s that way, but by incorporating Living Story into the Personal Story format there really wasn’t any way around it. The good news is if you redo it on another character you can get some of the big rewards again. This is especially nice for getting some of the Carapace pieces without having to save up thousands of Bandit Seals.
Bear in mind there are some bugs preventing progression in the achievements. One of them I came across last night was in the Meeting the Asura instance where the challenge mote refused to spawn. It’s been a bug since last December

FYI ANet support stated that you were opening the story, not the achievement with these episodes. Effectively removing pressure on themselves to fix it quickly.
