"Collected all Drawings" Achievement Bugged

[Destiny883]

I've found all the drawings in the game and I have unlocked all the single achievements concerning the drawings. However, the final achievement for collecting all of them didn't unlock for me. Anyone else experienced this?

I've already found a fix, if anyone's interested. The achievement didn't unlock for me the first time because I played the Prologue before the rest of the game; but after I replayed it, it unlocked! Developers should really think about fixing this.

Long story short, play the Prologue again and find all the drawings in it, and you should be fine.
