Upgraded to Unity 5.3.0f4 to receive "A connection has already been set as ready."

So, I just upgraded to Unity 5.3.0f4 and I’m seeing this error message:

“A connection has already been set as ready. There can only be one.
UnityEngine.Networking.NetworkIdentity:UNetStaticUpdate()”

I’m using uNET, anyone else experiencing this?

Found it! I was manually simulating a NetworkManagerHud Join Click, but that is no longer needed with Unity 5.3.0f4.
