Doing the 37 railtour appproaching Muirhouse North Junction I received an invalid aspect at the distant - a GG! Muirhouse North Junction distant by raretrack posted Jun 19, 2021 at 3:38 PM This is obviously a wrongside failure as you should only be able to get a GY, YG or YY. This also happened to me once before on another scenario / timetbale, but I thought I was seeing things then so didn't make a note of it. Would have been something in the Journey chapters anyway, as I'm doing all of those first.
Is Muirhouse North Junction the one where, leaving Glasgow Central, the routes to Pollokshields East and Pollokshields West diverge? If so, I have encountered the same bug. I think I've seen the same behavior in another scenario or timetable service before, but might be mistaken on that. At least the HUD is correct. (edited for spelling)
