The achievement tracker (when moved into the carbonite tracker) doesn't increment any longer. You fish a pool, the counter on the carb display never moves, but the wow one (if you open it manually) does.
Not sure when this one started, but its been bugging me a while, so its not from this last beta.
I, too, am seeing this. I have to open the Carbonite quest log to get it to refresh.
I've tried disabling the "Watch Achievements" options in Quest Module>Watch Options but the Blizz achieve list won't show up. Even after unwatching and rewatching.
