Description of the issue: Chest from a regular boss enemy (not the doppelganger or other level boss) spawned below the walkable floor area and fell into an unreachable position.
Screenshot: See attached; couldn't get close enough to get a picture of the chest itself, so I used a screenshot of the minimap.
Operating System: Windows 11
Platform: Steam
Game Version: v1.12.106 (17885342R)
