Spline Replication

[flygalaxies]

Hey Hey.

I am trying to spawn a an Actor that has a spline component with an RPC call, But when I enter the console command show spines’ It only shows on one of the clients.
Any ideas how I can add a spline on one client so it replicates to the other?

I have this code:

void ATrail::Tick(float DeltaTime)
{
	Super::Tick(DeltaTime);

	Server_AddTrail();
}

void ATrail::Server_AddTrail_Implementation()
{
	if (IsValid(TrailSpawn) && shouldGrow) {
		Spline->AddSplinePoint(TrailSpawn->GetComponentLocation(), ESplineCoordinateSpace::World, true);
	}
}

bool ATrail::Server_AddTrail_Validate()
{
	return true;
}
