I moved my cursor over my horse, typed "SetActorFullName Name", but it didn't work. Help?

My guess is that only works with named NPC's and not beasts.

I was just about to make my own thread but i'll hijack yours instead as its the same question.

I use setname Shadow to name my horse shadow and it works fine untill i reload a save (yes is did save first) and it just reverts the horse's name back to its default.
