Guild Wars 2

So I decided to do the LS2 EP 2 story on my warrior after I have completed it on my mesmer and when I did the “Discovering Scarlet’s Breakthrough” I unlocked two achivements when I yet have to complete the story first as it is stated in the journal

Was this an intended change or is it a bug that causes you to be able to unlock achives if you have done it on a different char already

Well, meta achievement tab unlocks, when finish the single personal story on any character once. So, maybe it’s not a certain bug, but ANet should lock an achievement progress on char, that’s not completed it’s own LS yet.

The same thing happened to me and my friend when we were doing that step with our alts. We couldn’t get the other achievements without completing the story mode first, though.
