The dead body lands on the horizontal door and plays the "landing from a fall" animation in a repeating cycle. It is very loud
and is the body's ghost poltergeisting in anger of its death. It is easily removed when they come to store the body, and could be spun as a poltergeist in anger of its death. I imagine it is a bug, though, so reporting it anyway. This was happening before, when I was in native 1080 60hertz resolution as well.
I imagine the body is encountering the door object, ending the fall. It sees the door is open, so no collision, starting fall again then encountering the door object again, forming a repeating cycle.
Thanks for reading,
Steps to Reproduce
1. build a ladder 2. build a horizontal door(any door) below or in between the ladder(deconstruct a ladder tile), with empty tiles below the door(or none, I imagine it will still do this if there are tiles directly below the door, as well) 3. have a duplicant die on the ladder, above the door - falling and landing on the door
