Steps To Reproduce
  1. Run attached physics_repro.Stratis mission with 2 players
  2. Player 1 (server) should select "Spawn object" from action menu
  3. Player 2 (client) should select "Spawn object" from action menu
  4. Both players should observe that object that belongs to other player starts to fly all over the place while their own object remains nearly still.

If nothing happens spawn more objects or try again but it should work with just two objects. You may also try to have only one player spawning several objects and they will appear almost motionless for their them while other player will see objects flying all over the place like a hurricane.

Additional Information

This happens not only when objects are on top of other objects like buildings but just on plain ground.

Example run of attached mission with 2 points of view
Player 1 (server, spawns Suitcase): http://www.youtube.com/watch?v=RdDGgKD6Lq8
Player 2 (client, spawns Fuel can): http://www.youtube.com/watch?v=bLaN6J3MxrA
as you can see non-local objects fly all over the place.

Can you please test this? It should be fixed in latest DEV (1.17.116538).
It should fix case with stationary objects. Not sure about those moving cars. That doesn't make much sense.

Thank you, Nesquick, it works amazing on current DEV version. Not sure if this fixed problems with cars but problem definitely exists and happens all the time on live servers. All our attempts to make a repro failed, we only have visual evidence and some testimony what triggers such vehicle behavior.

Awesome work nesquick!
