I've been making dialogue for some time now without issues but recently I noticed none of my NPCs make a sound when in combat. Easily fixed I thought, that should fit into the dialogue quest MISC entries under "Combat Grunts". I added a few "Arghsss" and "Oofffsss" and randomised them but nothing. NPCs don't make a peep. They do all the other dialogues such as Hellos, Goodbyes, Idles, etc but fight in silence. Am I in the wrong category?

EDIT: Title NOT grunting. Idiot me.
