We just released an update for the Deluxe Edition users which should trigger an asset download once you launch the game next. The asset download contains the 4 Deluxe Edition routes you have been waiting for.
Each route is made up of several parts of package and dependencies, so you will need to download the whole pack (all parts of the route and its dependencies) to get it working.
Routes added:
Avery Drexel (USA)
Season Town (Custom)
Warwick to Wallangarra (AUS)
Bidye Traction (Model Railway Scenario)
Enjoy :)
Regards.
