Vertical displacement bug on clients.
This one doesn’t happen on host, entities in motion up or down tends to continue moving towards that direction for a brief moment even after the motion stops.
Easiest place to recplicate this is at the righteous stand post coliseum elevator, players on clients might keep going up once the elevator stops.
video evidence of the same bug some place else:
in this case i had 200ms connection, as you can see the little rat jumped the fence but clipped through the floor on his way down and before his model was back up he was still able to hit me.
