OnPhotonSerializeView not updating properly [Values Pauses or jumps around

So I am using the OnPhotonSerializeView to sync our following Parameters. This script is owned by Master Client

public void OnPhotonSerializeView(PhotonStream stream, PhotonMessageInfo info)
{
if (stream.IsWriting)
{
stream.SendNext((float)GlobalOptions.currentNumberOfRound);
stream.SendNext(GlobalOptions.currentPrepPhase);
stream.SendNext((float)GlobalOptions.currentRoundDuration);
stream.SendNext(GlobalOptions.currentRoundEndWaitTime);
stream.SendNext(GlobalOptions.MatchEnded);
stream.SendNext(GlobalOptions.RoundEnded);
stream.SendNext(GlobalOptions.currentRoundToSwitch);
stream.SendNext((int)PlayerOptions.RedTeamWins);
stream.SendNext((int)PlayerOptions.BlueTeamWins);

}
if (stream.IsReading)
{
SyncNumberOfRound = (float)stream.ReceiveNext();
SyncPrepPhase = (float)stream.ReceiveNext();
SyncRoundDuration = (float)stream.ReceiveNext();
SyncRoundEndWait = (float)stream.ReceiveNext();
SyncMatchEnd = (bool)stream.ReceiveNext();
SyncRoundEnd = (bool)stream.ReceiveNext();
SyncRoundToSwitch = (float)stream.ReceiveNext();
SyncRedWins = (int)stream.ReceiveNext();
SyncBlueWins = (int)stream.ReceiveNext();
}
}

It works good for some time and then it gets stuck at random points
Now note this problem did not exist for all this time, and has appeared since we upgraded to PUN2

Now we have a backup code in every non master client's scripts to change host as soon as the current host's timer is not moving, this detects the synchronized version of the SyncPrepPhase /SyncRoundDuration /SyncRoundEndWait.

what is a better way to do this? or what am I doing wrong here? something updated in PUN2 that maybe I missed?
