Multiplayer problem

[NicuTapa]

Hello guys,
When i make a server with players or AI, i have strange problem with starting race : race start with rooling for 3 sec and after all cars collide between them. Whatever start i choose (roling, standing, formation) the race begin allways in this way.

Any advice is welcome

On all tracks?
Mod or stock content?

Only on addon track. In this case is Snetterton 200.
I thought it's a general problem but no
