Multiplayer weird skeletal mesh jitter

Hi folks,

I am working with UE4 about two months now and I have to say, I am absolutely excited about it. But lately I have some weird issue with jitterring whenever player step on skeletal mesh object. All skel mesh objects has phys asset with collisions.

In single player everything works OK, when i jump and landed on skel mesh everything is OK until I move. Below are attached two videos I make to properly describe situation.

Multiplayer (dedicated server + client):

Thanks for any help. :wink:

PS.: I deeply apologize for my english, I am not native speaker so I beg for your understanding :slight_smile:
