Are the nodes snapped together and about the height of your species CG off the floor? In my experience that really helps for a start. Will have more thorough look later. Ladder paths should be snapped to walk paths at both ends.
I think of paths as a railway track with your centre of gravity as the locomotive. If the station they're at is not linked to their destination station they have real trouble, as they do if the track wants them to scoot along the floor. They are not reliable at going cross country between stations, even a short distance. Sorry if you know all that already.
