I have been trying to find out how to cancel a trade route. I am playing as Yor in version 1.7. I have tried selecting the trade route in the Trade tab of the Govern menu screen, and then clicking the "Cancel Route" button, but this does nothing. I cannot find any option to cancel the route when talking to the race through the diplomacy screen.
Is there another method to accomplish this? Or are the Yor unable to cancel trade routes as a "Poor trader" race?
