Sometimes dead nodes get stuck with a route showing, not sure why.
Its not just the active routes you would want to look at, it would be the neighbors. Best way to see that is the z-wave mesh tool app [BETA] A Z-Wave Mesh Tool [C7 and 2.2.4+ Only]
The "Neighbor Of" info. Ideally that should be blank for a dead node. You might get some battery sensor devices that hang onto neighbors for a long time.
