So I have made 29 posted topics on this website including this one. And this is the seventh troubleshooting post I have made. Excluding mod request and some discussion things.
So I'm just gonna re-use this topic and remove problems or hide them away in the back once they get fixed.

Some of these problems may just be simple bugs in a mod I have and once fixed I could just upload them as patches to the nexus or contact the author of the mod.
Maybe some of these are already fixed by a newer version of the mod mentioned. However I will still bring them up.



All of the super mutants in the game make no sound when speaking. This is appearantly caused by a resource called Speedy Resource, used by the quest mod "War Trash"
I will now try to find out why that is using the geck and if everything is easy enough to do maybe provide a patch or something.
Of course I could just uninstall both mods after completing the quest.

Oh and here is a video.

Resolved fade to black issue:

If I'm not mistaken the fade to black is not present also because of ENB. I have heard of ENBs not allowing the fade to black and have even experienced it myself but I didn't think it was too gameplay intrusive. I've heard that it's to do with the adaptation settings but I don't know myself.

I would just complete the quest and uninstall it, I've had similar problems with the vanilla NPCs and quest mods. It's usually just compatibility not working right.

Have you tried validating your files on steam? It seems like the audio files could just be missing.

In the end I uninstalled it. 
It was one of those quests with shock value on important game characters dying and losing faction relations.
So I had no reason to keep the mod after going back to a previous save when completing it.

Aww, really? Well I'm glad your game works but I thought somebody would be happy the mutants are mutes? Super Mutants are annoying (Most of em at least besides some of the First Gen Mutants and Lily) anyways so I can understand your frustration. Now, do you have a video of the mutes? If so, make a comedy out of it. It would be funny.
