Since this Hotfix, the game says that I've not done the Headhunter quest yet for the "Howin Heaven's Name..." achievement.
I know I did it before the hotfix, but the star is no longer there.
This is sad as I've now done everything in that achievement now, but cannot obtain the Deco items and (what I really want) the "Al Howin Princess" title (oh and the Almoken's too).
The Headhunter quest/achievement was simple, just collect 30 of each of the 3 skulls and give to Katarina. I would even gladly do this again (as I have the max 99 of each skull on two characters) and both characters cannot get the Headhunter anymore. I've turned in the additional 10 of each skull to Katarina at least 10 times over and collected the 99 of each skulls again, but still nothing.
Sadida Emeralkat on this account is the one having the problem and my Foggernaut Yayakat on my second account are both having the same problem.
