I was wondering why the price of Wraith Ectoplasm rose again after plummeting to normal yesterday evening when the BD was "fixed" and the Wraiths started dropping items. And now I know - I battled both Wraiths at different difficulties with different pets - all kind of other items are dropped, coffers, codestones, food, but not a single Ectoplasm, Claw or Fur. No-thing. JS are just pathetic.
There is a cap now supposedly, so if you have a bunch of them already that could be why.
