An easy way to see this issue is by using several multiplayer clients
have several players on a server
position a player on an angled surface
kill the player on angled surface
each of the different multiplayer clients on the server will see a different simulation of the physics body
depending on the discrepency, certain players will be able to loot the body while others will 'see the body in the wrong place' and be unable to loot
note: this will not work on a flat surface, as there is no chance of the server simulation 'sliding' the body away far enough away from the resting position of each nearby client, so they will still be able to loot the body.
