Seems to be a common bug then, as I have exactly the same problem.
I thought the BH story was actually quite fun but the bugs I found at the end (this wasn't the only one) completely took the shine off.
QA generally seems to be quite poor overall, as there are lots of little (or not so little, depending on your viewpoint) bugs in places you would not expect them. i.e. in key class quests. If you are going to test anything as a priority, it would be all the class quests before the generic go-kill-x-bears quests. Since the game is being sold on the story experience as a USP, in their shoes you'd be testing all of this till it hurts, right? BW either has inadequate test teams and methods, or someone is making some seriously bad decisions when migrating code to live.
