So I just finished Matoya's Relict through the Duty Finder, but when the dungeon completed I didn't get a cutscene and now my game seems to be bugged with the "Like Master, Like Pupil" quest incomplete and no NPCs to be seen anywhere related to the Quest. I can't find Matoya's Relict on the Trust menu either, and I've already done the dungeon twice all the way through.

Has anyone else been stuck on a Main Story Quest before? I can't cancel and reaccept or anything, so I'm just stuck.
