I'd suggest installing the two manually as I did.
Just place all the files into LocalDisk(C:) > FeralHeart > Media > Models and replace all files. DO NOT COPY. DRAG THEM, IT'S BETTER.
Then restart your feralheart! The claws are attached to the mane, so no mane = no claws!
And for the wolves, the pelt color is same as claw color.
Hope this helped!
