Meaning of NetworkManager Warnings

Can anybody tell me what the warnings are all about?
I get them from the NetworkManager with LogLevel = Debug when I create a LAN host:

Ready with no player object
UnityEngine.Networking.NetworkIdentity:UNetStaticUpdate()

ClientScene::InternalAddPlayer: playerControllerId : 0
UnityEngine.Networking.NetworkIdentity:UNetStaticUpdate()

The strange thing is that the game runs fine on editor but it crashes on a build.

Been getting the same things. Does your screen also go a blanket color rather than changing scene?

Yea something like that…
It seems it’s stuck between scenes, somehow…

I’ve been seeing the same message but I managed to fix it. Make sure that your scenes are set up correctly in your Network Manager. In my case, I’ve been using NetworkLobbyManager and I’ve set the LobbyScene incorrectly.
