Hi all, Having a bit of a confused moment here, which I'm hoping is just a game bug. I'm running the S3 to Mammendorf (09:19 if it makes a difference) in the BR423, the first time I ran it I got PZB braked just after leaving Gernlinden. I restarted the service and left the HUD on. Sure enough, after passing the green signal after leaving Gernlinden, the HUD was telling me I needed to acknowledge a 1000Hz. The signal was green only, no speed limit displayed, nothing but green. Is this a bug, or am I missing some German signalling knowledge? Acknowledging the 1000Hz really slows me down too, and I can't seem to get to the next station on time as I can't get up to the track limit of 120km/h.
