When running the 92E i discovered a problem after you finish the timetable. If you run the last 92E service in the morning on your selected line, after the last service if you move to the next time slot both start route and end route are <no bus stops!>. Understandable as the route has stopped running until the afternoon. However, if i run the last service once i complete the timetable, it seems to move me onto this <no bus stops!> timetable, and i cannot cancel it. The only way to get out of this blank timetable is to exit the game and start again without buses. Quite an annoying problem.
