Starting rail vehicles with their initial destination being a terminal, where they will wait for a time slot. 4 copies of this convoy are made. All copies have their schedule checked and correctly show the terminal. The schedule is not mirrored or alternating. The result is that only the first train to start goes correctly to the terminal, with the rest wanting to go to various previous stops along the schedule.
Possibly the result of some kind of anti-deadlock system?
The schedule is constructured as a giant loop between 2 terminals, with the stops having dedicated platforms for each direction.
Can you upload a savegame for this, in which the lines and convoys are already made and just need to be dispatched?
