Ownership change - weird behaviour

From what I´ve observed until now I can say that the problem with multiple writing/reading switches occurs only when I am taking ownership. When I´m loosing it, everything is ok and the log goes perfectly from "OWNER" to "NOT OWNER".

Hi,

thanks for your interest about my problem! I just spent an hour checking behaviour of the ownership transfer demo and it looks like the problem is there as well. I´ve attached this script to the sphere which has PhotonView set to Takeover and Observe option to Unreliable:

public class TestBehaviourScript : Photon.PunBehaviour {

    public void OnPhotonSerializeView(PhotonStream stream, PhotonMessageInfo info)
    {
        // Always send transform (depending on reliability of the network view)
        Debug.LogFormat("IS BALL MINE? {0}  w:{1} r:{2}", IsCubeMine(), stream.isWriting, stream.isReading);
        if (stream.isWriting)
        {
            #region OwnerCheck
            Debug.Log("OWNER!");
            #endregion

            #region Info about position and rotation
            Vector3 pos = transform.localPosition;
            Quaternion rot = transform.localRotation;

            stream.Serialize(ref pos);
            stream.Serialize(ref rot);
            #endregion
        }
        // When receiving, buffer the information
        else
        {
            #region OwnerCheck
            Debug.Log("NOT OWNER!");
            #endregion

            #region Info about position and rotation
            Vector3 pos = Vector3.zero;
            Quaternion rot = Quaternion.identity;
            stream.Serialize(ref pos);
            stream.Serialize(ref rot);

            transform.localPosition = pos;
            transform.localRotation = rot;
            #endregion
        }
    }

    public bool IsCubeMine()
    {
        return (this.photonView.ownerId == PhotonNetwork.player.ID) ? true : false;
    }
}

I´ve also changed PhotonNetwork.sendRate and PhotonNetwork.sendRateOnSerialize to 20, just to make sure it is the same as in my project.

The result is almost the same as in my project - sometimes the log strings are changing unexpectedly - see the screenshot below that I took just after I clicked the sphere and I got ownership:

You can see that after ownership change evaluation it switches to "OWNER", but next call it is on "NOT OWNER" again. Another next call is switched to "OWNER" and it continues as expected. From my observation it seems like that send rate affects this behaviour, because I tried it also with default send rate (10 I think?) and I witnessed this problem like once from twenty attempts. After sendRate change I´m witnessing it much more often.

I know that colors are displaying who is the owner, but everything seems to be ok based on this indicator. The problem is just one call of OnPhotonSerializeView() which changes unexpectedly. You cannot see this by eye, that´s why I´m using debug logs.

Anyway, I just created new project, downloaded PUN package from the asset store and I´ve tried to replicate the problem on the fresh project. In the end I found out that this problem occurs only on non-master client. Can you please try to replicate it following this steps I´ve done?:
1)Download PUN package from asset store, import it to the clear project
2)Open DemoChangeOwnerScene, in the script ConnectAndJoinRandom.cs add these lines to Start method:

        PhotonNetwork.logLevel = PhotonLogLevel.Full;
        PhotonNetwork.sendRate = 20;
        PhotonNetwork.sendRateOnSerialize = 20;

3)GameObject OwnershipSphere, change PhotonView observe option to Unreliable
4)Add the script from my previous post (that one with OWNER logs) to the OwnershipSphere, let it being observed by PhotonView. Delete/comment part with position and rotation serialization, this is already covered by observing Transform of the object - so the final script will contain only Log.Debug() calls.
5) Make the build and start it as a master client, then hit play in the editor and join the room.
6) You are not master in the editor instance and the sphere is not yours, so click the sphere, obtain ownership and take a look in the console. I did it like this right now and the logs gave me this:

It was first time I clicked the sphere and it seems like there are two unexpected "NOT OWNER" logs (sometimes there is only one and sometimes it is totally ok). Can you let me know if you can replicate this behaviour? Thanks again for helping!
