I played some routes that were going off the map. As I finished the service and I decided to go back exploring whilst the AI was taking over, the train went, I was on the platform, not on the train and is suddenly said that I had reached the edge of the represented area. This bug needs to be sorted as I could explore the station. And the second Bug for TSW was when I took over the train, the bar that tells you the next station and the time went missing, and the objective marker wasn't there, so the service was impossible to complete.
I think you've posted the same thing twice Which routes, and which services, does it happen most on? Can't say I've experienced anything like this myself (Series X).
