When I am driving a timetable and have finished it and therefore create a new one via the same session, my Timetable does not load the new one after pressing T. And it also keeps indicating On foot instead of the timetable details.
I noticed that too, during the last couple of days. It doesn't seem to be route-specific, I encountered it on Mannheim-Kaiserslautern, Aschaffenburg-Gemünden, Maintalbahn, Mittenwaldbahn and Bremen-Oldenburg so far. Looks like a bug which crept in during the last update.
I've experienced that on every route. It doesn't work in the editor either. So I think they took out something that couldn't be done.
I also have the same problem on every route and every time. The new schedule simply does not load after using the “RETURN TO FREE ROAM” option. This is a very annoying bug for me, because I often use the “RETURN TO FREE ROAM” option while going back and forth on short local routes (for example Cathcart Circle Lines)
