I believe, it might be the clothing mods, since I am facing a similar problem, although in my case, it also concerns regular settlers. I assumethat some clothing options like "scarfs or pilot googles" are interpreted as fully clothed. Though I could be wrong and this is just a preview of the clothing-optional Settlement we are going to find in Chapter II.Ok one final point, from the look of things all of my clump went to different settlements,
one question about the visitors, do I have my clothing mods causing unintended consequences, or are seamstresses a reference to Disk World? Because they are Wearing a minimal Amount of otherwise colorful clothing, and Making me want to be EXTREMELY POLITE TO THEM Because the last thing I want is inevitable retribution from Dottie and Sadie!
