Launcher 0.3.17: please update
Launcher 0.3.17 fixes "wrong player ID" and "can't connect" after the game setup step, and sets up more copies of the game instead of blocking them. Everyone needs to update.
Launcher 0.3.17 fixes a problem where, after the launcher set up your game, Nation could show the wrong player ID or fail to connect.
If your copy of the game has a Steam file the launcher does not recognise, it no longer blocks you. It offers the one-click game setup instead, and you can undo it in Settings.
0.3.17 is now required: older launchers show "update required" and won't start the game. Open the Nation launcher and it updates itself, or download 0.3.17 from the Download page.
If you still can't connect after updating, type /ticket create in any channel of the Nation Discord.
