It's my fault for pressing buttons too fast. Anyway I shut everything down including the battery to do a hardware reset, but still the same. The doors stayed open and won't close. Reset ie restart the service is the only way here? Doors open and close right side ok. Just on the left they won't. The left is where I closed them early and then opened them again. Because the HUD door timer stopped. Seems like you NEED to close the MCB everytime you do a service with this. On all other routes you don't.
If you do things too quickly or you make a mistake opening and closing doors on the wrong side, then the 1442 from rapid transit will bug out unfortunately. Restarting is the only way you can progress. Same thing is required on rapid transit as well. You should be able to use the red 442 which works much better
You might as well spawn the Red VVO version to get around it. Report this as a bug/technical error. For the Red VVO version cold start reboot works. Happened to me once when I did an RE15/18 service from Großenhain Cottbuser Bahnhof to Dresden Hbf where I had a deadweight on the back. Upon the Cold Start Reboot the rear unit worked
