Mor'ladim quest not appearing

I am currently working through the Darkwood quests achievement. I only have the Mor’ladim quest left to complete, however Commander Althea isn’t giving me an option to start it. How do I get around this?

Were you able to do both “The Weathered Grave” and “Morgan Ladimore” quests? If so, do you have any other quests possible causing phasing problems in Duskwood? (Some of the Legion Artifact and order hall quests involve Duskwood.)
