I just recently ran into the mage in the Chorrol MG... he's got some serious issues. From what I can tell, the BSAs aren't working right - I have no voice, no meshes, and his eyes were all googly. I checked and all the BSAs are in the Data folder, so I can't figure out what's going wrong.
Files in BSAs don't always work. Try unpacking the BSA and see if that helps. If not check out the character in TES4EDIT and check that the meshes of his items have the correct file paths.
