ah sorry i'm wrong it's like this. Import these from the original TLAD anim.img (TLAD/pc/anim) to original IV anim.img (pc/anim): facials@f_hi.wad, facials@f_lo.wad, facials@m_hi.wad, facials@m_lo.wad, visemes@f_hi.wad, visemes@f_lo.wad, visemes@m_hi.wad, visemes@m_lo.wad..
Hope it helps.. But don't forget to backup because if you want Niko back you need those files..
Its the facial animations that causes the problem..
