Thing is, I've been seeing this issue happening to a specific roundabout again and again, and it effectively gridlocks my entire train network. I know, I know it should have redundancies to prevent that, but... well.
Here, you can see a train stopped at a specific signal.

Here, you can see the roundabout without the train, a few moments after I told it to follow another path (which it merrily did)

The save attached has the character in the appointed place.
If it is something stupid I did when designing it, please let me know
