While in the Grasp of Avarice dungeon on Master, a teammate finished the scorch captain a little close to, or just off the edge of a second level platform on the left side of the arena. When the captain died and dropped the scorch cannon, the cannon instantly teleported up to the roof of the arena. We could not reach it via jumping or super, and it failed to despawn at any point and/or respawn the scorch captain in the 20 minutes we spent attempting to reach it. Forced us to ditch the run and start from the boss checkpoint which was kind of a bummer.
