In Rhein Ruhr Osten, the door indicator on the HUD does not work for the BR 422. Regardless of what doors are open, the HUD indicators do not illuminate.
Maybe it is a similar issue like with the BR 66? There are two trains that are basically the same, but have minor differences (east coast way and great western espress) and apparently you can't get everything working on GWE with the ECW loco. May I ask if you own HRR? I already heard that occasionally you will only have the HRR passenger information screens with the 422 on RRO, this might be a similar issue? It spawns the HRR train on RRO and thus bugs out the door visuals on the HUD?
Okay, maybe send a ticket to DTG, asking them if they can replicate the door and information screen info issue when spawning a HRR 422 on RRO? If you have, with a picture of the missing door visual would be perfect. Maybe we are on to something.
I also own HRR. I'll check the PIS options when the door HUD fails to illuminate and see if it is the HRR train instead. I recall Matt trying to set the PIS on RRO and being presented with the HRR options, so this might be the issue.
