free roam self switching junction

[RBendo]

Hi, i'm playing with my own made route, well, in free roam scenario, every time some junctions switch automatically on a different route than the one I have set. Why is this happening? it's frustrating. Is there a way to block junctions during free roam? thanks

Do you have any AI trains running? If so, they will set the junctions at start up for their route and you will not be able to switch them until that AI train has run it's route. I believe that is how it works in freeroam. If you don't any any AI, then I do not know why they would be set and locked.

There are some other consists with engineer marker, but without the workorder, they don't run in free roam. The problem is simple, for each station of the route, i set all junctions on main direction, but in some of these, the game re-set the junction on a divert path, just when I am near the first junction, after passing the distant signal: derailment is not a choice.
