The game achievements say that I've completed "Forgotten Trophy" quest to get Pierce. Although I do not recall playing this mission nor do I have Pierce available. When I click on Pierce in the Companions tab, all it says is that Pierce dropped out of contact. Did I miss something or do something wrong ?

I'd really like to get Pierce but I don't seem to be able to.

Been a while since you posted this.

Same here, did dig up an old Jugg and I have the same issue.

I can use mine to send on missions but I can use him as Comp.

any other know why ?

Tried to look but can't find any info.

The obvious reason is that the achievement means that *one* character (not necessarily even a Mara/Jugg) has done the alert.(1)(2) It does not mean that the character who is looking at the achievement page has done it.

(1) In my case, I got post-KotFE Pierce for the first time on a *Sorc*.

(2) Achievements are shared across the whole legacy.
