The Final Pieces - NOT fixed

I am working 'the Final Pieces" as a hunter I have two options Boneshatter or Umbrahide. I wanted to make Umbrahide - and the quest did not recognize I created piece or a purchased piece as a ‘vessel’… I had to purchase Boneshatter to get the quest to finish.

As a side note: The category in this form makes no sense… where is standard bug report?
