Villager home issue

Big villages that generate give some of the villagers AI issues. Some times if the central area of the village is seperated of the other half of the village (with the houses of the villagers) by a cliff the villagers either dont know how to get to the meeting ( central area ) or they get there but dont know how to get back. Ive tested this a few days ago and they keep walking around the central area in the middle of the night and "interact with eachother" when they should be looking for their houses. Also since these villagers cant find their homes properly they cant find their workstations, especially the farmers. I suggeat fixing this with giving the villager taking the longer route/path ( if possible ) so he can get to the destination he's looking for. Also if needed I can give a seed for this and sorry for my bad english. Hope this gets fixed!
