ClientRpc not triggered after Reconnecting

Hi,

I am quite new to Unity and already struggling with the network communication. I plan to set some player properties, when a new client connects. In this stripped down example, I simply set the rotation of the current client GameObject.

According to the documentation, ClientRpc Commands are executed on all clients objects - also in the server instance. When I host the game using the NetworkManager HUD, the scripted player rotation is correctly set as expected.
However, when I stop and reconnect the host session, my ClientRpc call is not triggered anymore. The rotation command is not executed. See the 30 seconds video attached.


PlayerController.cs

Code (CSharp):

1.     ...
2.     using UnityEngine.Networking;
3.  
4.     public class PlayerController : NetworkBehaviour {
5.         void Start () {
6.             GameManager.instance.registerPlayer (gameObject);
7.         }
8.     }

GameManager.cs

Code (CSharp):

1.     ...
2.     using UnityEngine.Networking;
3.    
4.     public class GameManager : NetworkBehaviour {
5.    
6.         public static GameManager instance;
7.    
8.         void Awake() {
9.             instance = this;
10.         }
11.        
12.         public void registerPlayer(GameObject player) {
13.             Debug.Log ("registerPlayer");
14.             RpcPosition (player);
15.         }
16.    
17.         [ClientRpc]
18.         public void RpcPosition(GameObject player) {
19.             player.transform.Rotate(new Vector3 (45, 45, 45));
20.         }
21.     }
22.  

I do not know if this behaviour is intended or if I did/understood something wrong.
Of course, setting a rotation could be done in a different manner, but I am using ClientRpc calls for a different purpose in my project when new clients join a game.

I also posted this question in the Unity answers area 3 days ago. As there was no response (and the question slowly disappears in the further pages), I am trying my luck here.
