So, after enjoying the new routes in TSW5 I was about to go back to slightly older DLC:s and tried the Foul Weather Freight scenario on Hamburg-Lübeck. Going from Rothenburgsort yard I was joining the mainline and got red signal. After waiting some time and not seeing any AI I opened the map just to discover that every train on the whole map is stuck on the red light. Including the RB train that should bypass me. I never tried that scenario on TSW4, so I don't know if the bug was introduced with TSW5. Some others maybe have done it back then, can't find any older post about this issue?
Just letting you know I just finished this scenario in TSW4, all went smooth for the most part, in a few areas it was a task to keep the speed up for some reason, it was like the transmission was disengaged and I had to throttle down to 0 and reset it to Knoch 2 to get my speed up again. But I was able to complete it. At the final destination.
Ah, ok, then maybe something in TSW5 broke the scenario for me. Never seen problem like this before where all of the trains are stopped on red.
