Most of my newly created NPCs won't leave their house or enter my custom ones (my follower needs me to fast-travel to locations to follow, and one bard won't get out of her place and go to the nearby inn and sing (well, she doesn't want to sing either when a the inn, but I guess that's another topic...)
Also, while talking of unrelated topics, does anyone has issues with smithing since patch 1.5? My smithing went from lvl 20 to 56 by forging a steel shield and one set of imperial bracers.... I find it a bit exagerated, and I guess it cannot be a mod since my only ''smithing related'' mod is related to clothing...
So I guess I should have called this topic ''general wondering'' but heh, my NPCs really are too shy

Cheers!

I did finalize the navmesh for the interior cell and exterior cell, there are green triangles at all doors, touching the door.
