This was usually Immersive Citizens for me. But usually only when it rained and only the guys outside. If you can hunt them down when they go missing I might be able to override whatever they're doing. Get the Ref ID of one that's missing and do: Player.MoveTo xxxxxxxx Then enable debug mode in SLS and hit them with the newly added 'Get Actor Package' spell.  This will display what package they're running, it's associated quest and what mod it's from.  Many thanks I'l
