Six. Six of my settlers at Sanctuary have turned into feral ghouls. Maybe more elsewhere, haven't checked. I'm flummoxed. There they are, happily naked, hanging around the bar creeping the regulars out. (The population went from 21 to 15 too.) They don't say anything. They don't attack anything. They even take the walk of shame down the main road like all the other settlers, they are just really quiet and ugly AF. I can't interact with them, you only get the dot when you mouse hover over them and if you activate vats it catches them and they are named "Settler." (And if you kill one everyone gets all homicidal and s***. EVERYONE.) Anyone seen this? Must have happened a while back as any rollback's I've done they are still there. They ain't hurtin' nothing as far as I can tell and the other settlers only seem to know they exist if you kill one. (Run) So I guess they can stay, for now. It's still weird. Edit: I think this is the mod "Portable Cloning Device" causing this. Still looking into it, but I'm pretty convinced. Just in case someone else is looking.
