    TLDR
    Don't EVER call Awake() in a custom NetworkManager!


    So after a lot of testing I think I finally tracked down the source of my problems. If you have a custom Network Manager that inherits from NetworkManager it appears to override NetworkManager's base initialization if you call your own initialization during Awake(). This causes things like the NetworkManager.singleton not to be set, and also causes SceneObjects not to be "spawned" when a scene is loaded. Calling Awake() in a NetworkManager child doesn't cause any warnings and the NetworkManager.Awake() method is not protected/public so it can't be called by the child... so this means you can't use Awake(). This post is just a heads up for anybody having the problem (it took me a long time to track it down!).

    Here's example code that appears ruin the NetworkManager.

    Code (csharp):
    1.  
    2. public class TestNetworkManager : NetworkManager
    3. {
    4.     private void Awake()
    5.     {
    6.         //This causes NetworkManager.Awake() not to be called, and doesn't initialize properly causing very strange behaviors...
    7.     }
    8. }
    9.

    Edit: It appears calling Awake() causes 3 bugs.
    -NetworkManager.singleton not being set
    -SceneObjects not spawning (NetworkServer.SpawnObjects() isn't automatically called)
    -NetworkServer.OnServerSceneChanged() does not get called

    I found out the hard way that if you do a
    Code (CSharp):
    1. public override void OnServerConnect(NetworkConnection conn)
    2. {
    3. //your code
    4. }
    The player prefaf is also not spawned. This does not apply to OnStartHost, OnStartClient, OnClientDisconnect, OnServerConnect or OnServerDisconnect. Only OnServerConnect. Weird.

    UNET seems more or less abandoned at this point. I've moved over to Steamworks.NET and had a lot better time (If you plan on using Steam anyhow).
