The conquest mod is one of my most must-haves, letting me build my settlements where I want them.
But the settlers wander off and half of them are still supposedly part ofthe settlement, but just aren't there.  
I've run out of ideas as to how to attract them back home.  Ringing the bell draws in like 7 or so, out of 17.  Beds and bars aren't enough to draw them home from wherever they went.  No idea where they are, but are either invisible or very far away.  
Any tips from conquest users on how to fix this?

Edit: The author has supposedly abandoned fallout 4 modding so questions on the mod's nexus page seem to be going unanswered.
