I under stand that. The point is if bethesda wants to make modding easy what are they doing saying oh the community fixed it look at there guide. They promised one click installs so any one could mod not editing files to gets stuff to work.
Maybe the hd pack was intended as being used without any other texture mods, for simplicity. For the guy who's happy with 1 pack.
Modding is an advanced feature as it is, and with a little research, as shown in my link, it's easily solved.
Or maybe they dropped the ball lol.
