There is an issue with the approach control to GRV platform 0 where you have to run really slowly and (very) close to the signal for it to actually change up to yellow Other than that I haven't had any issues Any particular runs you can give us so we can try to recreate? Service Time or headcode would do
That means all the 1Nxx services, so that's 2 per hour, every hour from 09:40 to 29:09 I've run several of those with no issues bar the approach control one listed above
