Bug description: When entering this area where the quest seems to have already started it will not give a 0/5 piwi's killed and thus the quest can not be completed. (I was able to clear it once before, which might have saved the "you have already cleared this challenge" state to my character)
Reproducibility: unsure, since the quest won't reset I do not know, exiting and re-entering the area is ineffective.
