The Hooded One not appearing after killing bosses in act 4.

As the title says, I am on The Search quest and when I kill one of the bosses The Hooded One doesn't show up to reclaim the weapon parts. I have spoken to him in Kingsmarch. When I do kill them, I see a puff of black smoke but his actual model doesn't appear. Anyone else have this issue, or know a fix? I am currently soft locked and cannot progress through the campaign, infuriatingly.

same issue, soft locked on all progress. Beyond infuriating; so do;;ne with this league -- worst l;aunch in history and clear proof GGG just doesNt care about 2.;0../;.
