Boss Week Achievement
Maybe you need to do another of the daily boss achieves. It’s usually either Tequatl or Tequatl/some other world boss. It alternates. Today is the Tequatl/other so try doing something like the Maw, Jungle wurm, Tequatl or other like this.
After reset, do the Daily Boss Week achievement, and you will probably fulfill your 9/9. You need 4 Dailies for the Meta achievement.
Also, several threads about this in Tequatl Rising sub-forum. =)
