Couldn't connect again after using disconnect. Bug?

CMR

When the game starts I call this method:

	private void SetOnlineMode()
	{
		if (PhotonNetwork.offlineMode == true || PhotonNetwork.connected == false)
		{
			PhotonNetwork.offlineMode = false;

			PhotonNetwork.ConnectUsingSettings("0.1");
		}
	}

Then when you press the singleplayer button I call this:

	private void SetOfflineMode()
	{
                if (PhotonNetwork.offlineMode == false && PhotonNetwork.connected == true)
		{
			PhotonNetwork.Disconnect();
		}

		PhotonNetwork.offlineMode = true;
	}

After playing singleplayer, when you return to the main menu, I call again SetOnlineMode(), but Photon doesn't connect again, this is the log:

OnStatusChanged: Connect current State: ConnectingToNameServer

Connected to NameServer.

OnStatusChanged: EncryptionEstablished current State: ConnectingToNameServer

Is this a bug?
