Hit this yesterday during multiplayer. As seen in the video, my character started to walk off the elevator and hit the edge of the platform as it began to descend. This caused me to take fall damage and go down in a way that my friends could not revive me. On their screen, I was in the middle of the pit, rather than stuck to the side.

Possible repro (haven't attempted to do this again)
- Have character stand on edge between elevator and platform
- Send elevator down
