[ufna]

FRigidBodyErrorCorrection was changed a lot, check 0331f17

void AVehicle::PostNetReceivePhysicState()
{
	// NOTE: we intentionally do not call base implementation here
	
	FRigidBodyState NewState;
	ReplicatedMovement.CopyTo(NewState);
	FVector DeltaPos(FVector::ZeroVector);
	
	GetVehicleMovement()->ConditionalApplyRigidBodyState(NewState, GetVehicleMovement()->PhysicErrorCorrection, DeltaPos);
}
