I've lost access to this route for some reason on my Xbox Series X. It says owned deluxe edition. I've uninstalled and reinstalled, but I can't see the route or either of the two locos in game. I've restarted my game twice now. The only route not appearing. I have 109 add-ons installed
If you go to the installed add-ons from the Xbox dashboard, is it listed there? On the dashboard select the game, press the hamburger button > Manage game and add-ons > Select the game tile and see if the checkbox is selected for this route. If it is selected and installed, did you close the game fully? With quick resume, the game is not fully closed, so you keep getting the same session. To fully close the game, select TSW7 from the dashbord, press the hamburger button and choose "Quit".
