Can't continue quest.
Everything is working as intended. You have encountered the “new player experience” which has somewhat re-organized and partitionned the story into 10lvl segments.
This means that your first act of the personal story will be unlocked when your character reaches level 10. After competing the first act you will encounter another “leveling phase” until you can continue with act 2.
Oh ok, thanks a lot. I wasn’t noticing anything out of the ordinary, except for the whole quest thing; so I decided to ask. Glad I did! Thanks!
