I recently purchased T:ANE SP1 on iMac off the App Store, then downloaded Legacy of the Burlington Northern off the game's featured route page. Route was $12.99, and after making that payment, the vanilla version of the route downloaded along with the necessary content packs. I opened up the first three content packs for the route, downloaded them, and installed them. After finishing the third pack, the window with these content packs vanished, and now I am unable to finish downloading the necessary content for this route to run. There are several trestles and railside objects missing, as well as all of the routes BN and UP locomotives. They show just as "missing dependencies". What has happened? These are all items that came with the route, but I cannot access them anymore. Is there any way I can?
