SyncVar and RPC calls allow a UNET server to send messages to clients, but these messages are not triggered if the server-side change comes from the inspector or a custom editor (and presumably any non-MonoBehaviour).
EG I use the inspector to change a SyncVar - only the server is updated. Or press a CustomEditor button which calls a method marked with Target/ClientRpc - it will just execute that method on the server.
What is the best way to call UNET networking functions from Inspector GUIs and non-MonoBehaviour code?
