Hunts not counting for achievements

[Knuddelchen]

Some hunts, espacially the ARR Hunts are not counting for the achievements, although you get the reward for killing the hunt the achievmentcounter does not increment.

[DrWho2010]

which hunts are you doing? B/A/S?
which achievements are you looking at?
please be more specific.

just tagging the mark even once is enough to make the counter go up by 1.
