By default, Twine will snap passage cards to the gridlines of the story map. If you'd like to disable this behavior, choose Details from the Story top toolbar tab and uncheck the Snap to Grid checkbox. This setting is specific to each story in your library, so one story can use grid snapping while another doesn't.
Grid snapping only affects passage cards when you move them. It doesn't affect the existing position of cards.
