My DE Necro has started this quest to get the Grobb neck. I noticed that when I collected the head of the traitor in Starfall and turned it in to Coordinator Malika, I received standing with Grobb Wardens and Denizens of Grobb but received no improved faction with Blackscale. From checking other posts here I thought this quest was supposed to improve Blackscale faction. Has this been changed or am I bugged?
