You can still unlock the "Collect 15 Forsaken Exotics" achievement by doing an exotic quest. Please fix the text description back, because it didn't always say that. It should mention that completing an exotic quest will pop it for people who like achievement hunting in a certain order. It looks weird to unlock 15 exotics before the achievement for 10. I'm not the only one with this problem either. It's affected many older accounts who did exotic quests for this achievement back in the day. Please change the achievement description.
