I’m running version 2.0.0.22370 x86_64.
If I go from Main Menu > Local Area Network > Create > Back
It takes me to the same menu as if I had gone to Main Menu > Single Player.
But you would expect it to take me back one step to the Local Area Network window, where I can see the current LAN lobbies.
This behaviour does work correctly when I go to Main Menu > Local Area Network > Load > Back.
