* Run shoulder check from "Map\Validate road shoulders" This will generate list of all items which could cause issues with random events (mostly models clipping through). You have following options:

** Mark the related road as having blocked shoulder ("Shoulder blocked" checkboxes in Road item properties) to prevent generation of events.
** If you do not care about the issues, you can ignore the item.
