Discovered a glitch which I cannot seem to workaround on the Riveria Line Timetable number 4 or 5 from the top. I think its the Laira depot to Plymouth or Painton part 2 - first stopping at a platform but there's a red light that does not change just before the platform after going through a yellow caution light. Waited there for about 20 mins before proceeding and getting a spad. Tried contacting the dispatcher by holding down B (Xbox series X) but it came up wait for the change. Is it a reported fault or is there something I need to do like change the points? Please help.
The rolling stock is a Class 802 GWR - its the 5A72 Laira Depot to Plymouth - Part 2. There must be something I am not aware of unless its a sticking clitch.
