The way the structures are placed in that area causes normal husks to glitch and go under the map. Still a work in progress to make it stable, as seen, husks want to break the block off. The glitch stops working if the block off breaks
after rewatching this video the glitch is gone if you remove the first ramp(edited cone) above the floor spike and put in a floor(ceiling) to prevent backwards flying husks from the floor launcher
