There may be something to do with the mods order in "addons",unfortunately I don't
know if reskins must be loaded top or below their respective required mods.

An other,safer way is to manually download the mod using steam workshop
downloader for instance,and extract the content in the (...)\nmrih\nmrih\custom
folder.
It's a bit of a hassle but not only it just works,it also gives Todd Howard nightmares.

Only shows the default overhaul instead of the black one
