Feature : makes impossible to receive messages before all the scene NetworkIdentity have been activated back.

[Paradoks-Studio]

This feature request is related to this :
#3601

It looks like mirror client side is trying to receive message before the scene NetworkIdentities are activated back via:
NetworkClient.ApplySpawnPayload()

I tried to track the message with :
RemoteCalls.RemoteProcedureCalls.GetDelegate(msgType)
it returns me "Null"

As a result the client is disconnected.

In NetworkClient.OnTransportData() i commented out:
connection.Disconnect(); - line 350
and added to my GameObject a debug utilitie with:
public void OnEnable(){Debug.Log("WhoActivated - OnEnable: " + gameObject.name, gameObject);}

i receive:
Unknown message id: 46251. This can happen if no handler was registered for this message. from NetworkClient.UnpackAndInvoke()
until the GameObject is activated back, then never anymore.

So the request is:
Can mirror prevent message receive until all NetworkIdentities are activated back ?

Is this related to scene changes? If so, how are you changing scenes on clients?

[Paradoks-Studio]

i change scene like this:
SceneManager.LoadScene()
the bug was not present in v66

[MrGadget1024]

If you send a SceneMessage from server to clients, or use Network Manager's ServerChangeScene method, then clients will suspend msg processing until the scene is loaded. Mirror has always been designed like this.

Frankly i don't remember exactly, it was a little while ago.
But, there was a problem with Mirror enabling/disabling/enabling again the scene objects.
So the gameobjects were enabled - ready to get message, disabled ( here comes the error ), enabled again.
and again, i did not touch anything between my v66 and my actual version ( maybe 81 or 82).
