This is the mission before “The Steel Tide”. I can’t check because my story panel is also broken, but that’s a separate bug report.
This mission has so many bugs, I wonder if there is any point typing it all out. I would rather just say a dev needs to go play it. I will try to be brief.
In order of chronology:
1. The armor column gets “attacked” in transit but does not stop when this happens, so your fighting undead while they roll off.
2. The first two cutscenes have very low voice overs and no subtitles.
3. You don’t really need to “defend” the column afterwards because their cannons kill most undead before they can get close. You can go the read a book or something.
4. What in kitten’s name is going on here? It seems like there was supposed to be some epic battle with these giants, but nothing happened.

5. The npcs speak of a ghost fire mechanic to kill the giants. It doesn’t seem to be implemented.
6. Tegwen says she will stay behind in the cutscene but follows you downhill anyway.
More and more people are getting to this point in the story Anet! Finishing it should be a top priority.
PS – Would love the ability to replay missions like GW1. That way I could one day play the completed version of this.
