PC Ntp Whistler An Gronk

Held at red signal HL 649 behind a service ahead at red signal.

I've played this scenario in the past with no problems?

 

Was that before the recent buffer update (post SoS release)?
A few services with freights sat at red now fail because it "clanks forward" fouls the signal in front of it which locks your path

 

Possibly before the update yeah.

 

I played and had no problems
