Mostly a curiosity now, although it would be nice to be able to go into testing mode without restarting to toggle mods. Code: $ server --state sandbox Coherent: (I was on start screen, which defines the necessary observes) Code: self.gameHostname('localhost'); self.gamePort('6543'); window.location.href = 'coui://ui/main/game/connect_to_game/connect_to_game.html'; At the moment I don't see a way to set the server state from a client mod, only lobby/Config and gw publish 'gameModes' that can be accessed from the client.
