I've been having this issue myself, most notably with Immersive Armors v7 and Winter is Coming. For IA7, all it unpacks is the ESP, no matching BSA or anything. For WiC it extracts everything but the textures, only meshes and the ESP, so I end up having a Skyrim full of people wearing big, shiny purple capes.I've manually solved both problems by extracting the files by hand, but it's still a hassle. MO didn't used to do this, as the first time I installed WiC it worked fine.I haven't changed any Extractor settings, either.
