So me and the Castle just aren't getting along at all. New settlers arriving will prompt the leader to place new residential plots down, but no job plots are being placed at all. I found two obvious areas for martial plots, so I set a couple there manually then ran away for a while. I come back now with two more settlers who showed up, and suddenly one of the martial plots that was supposed to be placed automatically by the leader overlaps one of the plots I placed manually. I don't know why it took forever for that plot to appear, but it did. So I scrapped mine and left the "planned" plot in place. But I am still down -3 in job plots. I don't know why The Castle is lagging behind on job plot placement, but it is.
As an aside, I don't know what caused this, but I lost Ronnie Shaw as the super vendor she is supposed to be. I think this was caused by her becoming a leader, because now she's commandable, takes residential plots and jobs, but at no time during her normal "business hours" can you use her as a vendor. I placed a commercial plot (weapons) and put her there, and her dialogue matches all of her normal vendor dialogue, but she doesn't have the same inventory (I did the same thing for a level 3 vanilla weapon shop). The long and the short of it is, The Last Minute isn't in her inventory in either case. So if you want that Gauss Rifle, I suggest you get it from her before doing any ROTC builds where she can be made leader, as that is going to mess her up. If someone knows a fix to this, I will gladly give you two whole pats on the back. I tried removing all leader mods and it didn't fix her. I assume she is broken at this point; just another named settler.
