I have researched this quest and additional quests picked up from the same location (Outhouse Hideout) on wowhead and currently the Gather the Intelligence quest is bugged, logging out and back in and fully restarting the client do not resolve the issue. Other players have had to submit a ticket and have a GM add the quest item to their bags.
Unfortunately there were more quests from this Outhouse Hideout source than I originally knew about. Simply commenting out Gather the Intelligence and Seeds of Discord will not resolve the interrupted questing flow because there are several additional quests picked up from that same location. Speech Writing for Dummies and Head of the Class are also picked up from this location. Head of the Class is the first in a quest chain which are all in the questing profile as well (
Head of the Class - Quest - World of Warcraft). I am commenting out all of the related quests and testing the profile without these quests to temporarily circumvent the WoW bug. I'll post again if the profile continues to work without these quests.
Looks like this doesn't work either, I believe Slash and Burn (part of the Head of the Class quest chain) is required for phasing for further questing. Will troubleshoot more later.
