Since last nightly time interval choose signals appear critically broken. Practically all the train networks on the server have stopped working due to trains entering occupied platforms.
It appears they cannot see other unocupied platforms, and when an ocupied platform has a reversing train they send another train into it causing a deadlock. Additionally reservations by the choose signal are not being cleaned properly.
Someone says this can be fixed by completely selling all trains, remaking the line and starting again. I somehow doubt this is the case.
This looks serious enough for an emergency update!
Restart with fix in progress now.
One must rebuild the platform choose signals for them to work correctly, otherwise they will continue exhibiting buggy behaviour.
After losing ~5 million on the server, it looks like services can finally go back to normal.
Apologies for the difficulties: I am glad that it is working for you now.
