PTJ Job Impossible In Bangor?

So when I've been trying to do his part time job in Barri I haven't been getting any more goblins to spawn. I think you might have to go to another dungeon to do this job. edit: more specifically, since the dungeons were changed.

I've data mined the floor plan of the regular barri dungeon, post renewal, and while I can't find goblins spawning on the first floor, they do spawn on the second.

The first three rooms of the second floor, for example, must spawn goblins, along with other creatures.
