DontDestroyOnLoad NetworkManager Bug 5.5.0f3

Question

ERROR:

InvalidOperationException: The following game object is invoking the DontDestroyOnLoad method: NetworkManager. Notice that DontDestroyOnLoad can only be used in play mode and, as such, cannot be part of an editor script. UnityEngine.Networking.NetworkManager.InitializeSingleton () (at /Users/builduser/buildslave/unity/build/Extensions/Networking/Runtime/NetworkManager.cs:196) UnityEngine.Networking.NetworkManager.UpdateScene () (at /Users/builduser/buildslave/unity/build/Extensions/Networking/Runtime/NetworkManager.cs:729) UnityEngine.Networking.NetworkIdentity.UNetStaticUpdate () (at /Users/builduser/buildslave/unity/build/Extensions/Networking/Runtime/NetworkIdentity.cs:1074)

WARNING:

NetworkManager detected a script reload in the editor. This has caused the network to be shut down. UnityEngine.Networking.NetworkIdentity:UNetStaticUpdate()

Supposedly this was fixed a few versions ago: https://issuetracker.unity3d.com/issues/multiplayer-invalidoperationexception-when-select-neworkmanager-in-hierarchy-for-the-first-time

Unity Version: 5.5.0f3

We cannot get this same bug to occur in our developer's Windows Unity 5.4.1f, it only occurs in our new version 5.5.0f3.

We have also tested in 5.4.3f1 on a MAC and it does not occur. So it seems to be related to the latest build. 5.5.0f3 (mac).

Come to find out, it had NOTHING to do with our version of Unity and everything it seems to do with starting the project in WINDOWS Unity and copying the project files to use with $$anonymous$$AC Unity.

We are now testing in Windows (the OS-Unity setup we originally built the game in)... and so far ZERO bugs, ZERO issues. So this suggests that you CANNOT copy a project from one OS to another and have it work seamlessly.

We are talking about many issues: networking not working graphics super laggy UNET problems strange errors that were fixed many patches ago...
