PC Tsw2 Schnellfahrstrecke Köln-aachen Can't Continue With Save From Aachen Turnaround

Yesterday night, I saved a situation on the Aachen turnaroun scenario, with the train stopped at a station, and the left doors open. Today, I can't continue from this save, because I can't close the doors, and the throttle also does nothing, and its indicator stays red.
This goes wrong since the latest TSW2 update.

 

The save feature is broken at this point best not to save if you can avoid it.
