A couple thing I haven't figured out:

(1) When I first bought a horse, it said I could name the horse, but I didn't see anyplace on the screen to do it then, and found nothing in "help" about it.

(2) Last time I gave Lucia a dress, it turned into a two-piece bikini-like outfit, somewhat like forsworn armor. Is this normal, like a sign that Lucia is growing up, or a bug?

i think you can name your horse with a mod. check the system menu mod configs to see if you have it and if you can

Im thinking bug maybe a mod as the vanilla kids are supposed to be fully clothed to keep the creeps from having them naked. even without mods i have seen them go naked. give another dress or stay away for awhile. i cant remember what i did to actually get her to wear clothing again

1. You can not name your horse in vanilla game. You can name them with Convenient Horses and Convenient Horse Herding installed.

2. Kids do not grow in Skyrim and clothes should not change for child race characters (children are dealt as a race of their own.) You likely have a mod that modfies child race and for some reason allows them to wear clothes like adult females of other races do.

btw when i said naked i meant halter top and undies

If she is in her undies, then most likely the dress texture is not compatible, corrupt or possibly a mod is interfering.

I think something is wrong with one of the dresses. I gave her another dress and the problem went away. Later it happened again, but this time it went away a few minutes later by itself. It's only happened at Lakeview Manor, if that would have anything to do with it.

BTW, all dresses should be vanilla. As far as I know, I don't have any mods that affect children.
