I was working on my Industrial Harbor route, and suddenly when I was switching from the editor and back into a free roam scenario, all the in the entire route were gone. I used a couple different track sets, and they all disappeared. In the free roam, some rolling stock still shows but the 2D map shows no tracks at all, no markers, etc. and when I try to run the free roam I get an error message about broken consists. If I try to add rolling stock, nothing even shows for me to place.
Does anyone know how to fix this? I have a ton of hours into this route.
