Guild Wars 2

Silmar Alech Hi and thx for your reply.
I am indeed aware of that. I really did collect all the books. The proper books, not the popups texts. I counted all 10 times that my character is “opening” the books (you get a small bar charging above your utility skills), I got all the 10 differents books, and one of them (the Section 8 for me) is bugged, and did not counted towards the achievement.

I just re-tried for the second time, and I have the same issue.
I have interacted with all 10 books, but achievement stays at 9/10. For me, Section 8 does not appear as collected in the Achivements panel, and i can’t read it from the book inmy inventory either.
Although I’m positive I collected it in the instance.
Hope we get a fix soon
