I reenabled Living Settlements after the update. Now I’m thinking my base is too spread out.
Top distance is the Onsen Resort. Thralls can’t seem to make up their minds. They might move 10 meters (20 max) before turning around or changing destinations, wherever that may be. Maybe they need floating emoticons 
.
Anyway I did notice a Thrall still getting stuck on the Tinker’s Bench (small Sepermeru 3rd base).
When she moves in the opposite direction, she does not get stuck.
