Why doesn't the new Livonia route that I just bought not show up under the Standard or Free Roam tabs? I constantly have problems getting not just this route, but many routes to appear there. Sometimes they do, sometimes they don't. Is there an explanation for this?
It's possibly because all scenarios are Career scenarios, so they will appear under Career. See below from the route DLC page. If you want to have scenarios under Standard or Free Roam, you will either have to make your own or download from the workshop. Being a fairly new route, I'm not sure how much will be there.
True, but I wasn't sure what joker's experience with the game was. If you do this, joker, make sure to save a copy of the scenario so you can still play the career version, which stays in the pack anyway. You'll need to extract all of the scenarios before you can edit anyway, and making a copy is the safest way to make sure you can maintain your version (same policy editing workshop ones).
