In this updated version, I believe I have fixed;

 - Nigel not being functional at all as a follower.
 - Nigel's voice lines never getting used in any circumstance. 
 - Nigel's Face textures looking as though they are missing or just being fucked in general. 

Let me know if these issues particular issues are still persisting or any other issues you may notice do show up, I'll do what I can to fix them. 

Thanks!
