Guild Wars 2

I have collected all five stories of part one of the scavenge hunt, got the book on one of my characters and now its impossible for me to do it on other chars cos Magister Tassi does not want to accept the stories to make the book.
I have all five, i tried on more then one characters and my friends have the same problem.
What gives?
This has been going on for five patches now.
Its about time its fixed cos this just frusterate people who spend time and effort to collect all the pages.

There are six pages to the book. Did you get the one from serene (next to tassi in LA)

….Well i sure feel stupid now. I was thrown off by the fact that there are five location clues. Nevermind this, it works. Im just derping. <.<
