Guild Wars 2

I finished the story yesterday and today i hoped to work on some of the achievements. These require me to go to The Bitter Cold. So i want to remake the elixir so i’m able to go there but i cant seem to get any frostbitten suet anymore. i’ve killed tons of mobs all over the map but none seem to drop. Someone told me to redo the story up until that point, but i redid Precocious Aurene and then went to the map (even going from Forstgorge) but that didnt help either.

There is another thread on this issue. The Elixir making daily quest is bugged/
