Got to the point where I had to follow the raven, followed it to GhostClaw, spoke to him and nothing happened - it doesn't update, and he is not in Thundering Steppes where he is supposed to be. Skyfire, toon Othelleo.
You're right, WildSage. Ghostclaw would have the quest update icon, if following the mysterious raven had updated. Somehow it had not. If you are to return to Erus is he able to spawn the raven again? If so, speak with the raven and walk behind. If and when the raven stops walking, approach it again. That should be enough for it to move forward. (Don't hail it or interrupt it as it is pathing, as that can just force it to take longer.) Hopefully this time when you follow it all the way to Ghostclaw, he will then have the proper quest update icon and conversation waiting for you. ~ Kaitheel
