If I start a service on HRR and I use the DISPATCHER command (hold B on Xbox controller) I'll change all, or almost all, the signal aspects along my route. All these signals will turn automatically in red, also if I can continue to run my service, because for TSW2 system all those reds are still (correctely) green and/or yellows. Please, keep attention on this screens. Pic 1: Here I move the train without hold the dispatcher button (all looks correct) Pic 2: Just 10 meters forward I hold B (I contact the dispatcher) and thats the result. The first aspect still looks partially correct, because it tell me the train will take a deviation track - proceed at reduced speed (yellow on hud insted green) because you have to change track, in this case at max 60km/h (PZB restrictions not included). Pic 3: from here 'till Bochum every single aspect will become bugged/red! But only for the line, because for the system (look at the hud) all these reds are correctely greens and/or yellows. And I can overpass all these reds until Bochum Hbf without the "service failure" penalty. I know, this bug its amazing! Note: Im on Xbox One X but I suspect this is an HRR "core" bug.
It's a bug on both HRR and RSN. I wouldn't be surprised if all preserved German routes have this issue...
I'll have to try that now! see it I can get it to do the same......this poor preservation team are going to be rushed off their feet!
