I’m probably bad at designing 🙂
Anyway, I just noticed something…which explains what I was seeing…
On one of my routes, I toggled the lights to one way only, as expected the route changed.. Â I toggled it again and the route changed again, to something different, not the original.. so I repeatedly toggled the lights and it went through a a few possible routes for one of my lines, including the original.
So this explains why making a change and reverting it can leave your lines messed up
Below with no other changes, the game gives two different routes for the red line with the same signal status of ‘two-way’
This also changes the route of another line(not shown) between two tracks.
The same things occur by making a change to the track layout and reverting, not just toggling a light.
