The noexit is a door (or should have been tagged as a door) into the building and is connected by internal corridor to a door on the other side.  I did note it's an isolated route (didn't get the warning probably because it's an internal corridor) and connected the doors to the surrounding footpaths if that helps, or does it need something else done to fix it?
