I know you're aware of this but I just want to know if you plan to fix this and I have a partial solution(I think). Not even the shared shaders are loading. I did find if I packed an IMG file and placed it in the root of the update folder it loaded in the DLCs. I only tested this with the old Fusion Fix which had the illuminated BAWSAQ sign in Star Junction. Unfortunately this would only work with shared assets.
