NPC SyncDirection .authority is false

repro:

• Tanks demo
• drag Tank into scene, name it SceneTank
• add log message:

        void Start()
        {
            Debug.LogWarning($"{name} hasAuthority={hasAuthority} isOwned={isOwned} authority={authority}");
        }

it works properly for the player's tanks.
for the NPC in the scene, it's always false.
even though server owns it.
