Finished this quest 2-3 days ago without issue. Be sure you follow the directions on the wiki, there are a few different NPCs you hand into, and it swaps back and forth a few times.
Are you talking about Master Whoopal's in Nek? Loot his head and hand it to Draxiz N'Ryt (not Ithvol K`Jasn) in Neriak Commons and you get "Skinned Halfling Face Mask"
