Have you ever made a change in the Corridors>View/Edit Corridor Section, such as deleting a link at a certain station, then wanted to get rid of it and couldn’t figure out how?
It’s a little bit hidden. Find out where to make the change after the jump.
In the scarcely explored “far right” of the Corridor Properties box, there is an overrides column.
Click on the overrides for the right region, and you can erase your manual edits.
