A train that breaks down while crossing the map border no longer blocks the border for good. Trains that can't stop fully on the map no longer break down there.
A service loco following another train on its maintenance route no longer skips ahead and requests a route from a later signal while it waits for a block to clear.
Contracts
Closing the contract editor no longer deletes a blueprint whose first stop passed while time was running.
Multiplayer
Your train alert settings no longer reset to the host's when the host loads, restarts or starts a new game.
Interface
Upcoming Trains tabs no longer overlap or space unevenly after a train enters the map.
