Yesterday I achieved exalted with Honorbound, went to Orgrimar and got the quest from Eitrig to talk to Anachronos. After talking with Anachronos he sent me to the dark portal.
I clicked on the portal and found and beat Guldan. Then nothing happened. I logged out, logged back in. Left the zone and came back. The quest did not progress.
I decided to abandon the quest to start over, now I don’t see Eitrig in Orgrimar and don’t have the quest to talk to Anachronos.
I opened a bug on the forums yesterday but have received no response. Please look into this and get my character unstuck from this broken state, thanks.
Posting/reporting bugs is excellent, thank you - but you don’t get ‘action’ there, those are for QA to have a look to fix an issue, not necessarily an individual case.
If you abandoned a quest, you should be able to pick it up at the point you received it. Have you done a proper reset UI by chance? It is not outside the realm of possibility this could be a UI issue as well.
