Awesome. You should specify in which service, weather time of day, location and so on. That makes it possible to reproduce this. As a bug report this is not useable.
I often see this on bakerloo on board a train. It’s when the AI figures are too close to a light source in the current scene. For bakerloo, it’s the coach internal lights shining on the characters standing in the doorways.
I think this is something to do with the baking of tunnels in UE , not sure if anything can be done about this
I tell you what. If I would be doing a late service and started on foot, would go down in the underpass or even walk on a empty station, and I would see that it would scare the living daylights out of me !!. That is creepy!
