Hi, I know this isn't great news but I am currently unable to fix the mod due to my laptop being in a nearly unusable state for the past couple of months. I have also generally stopped caring about the game in general, so me actually releasing an update regardless is a pretty slim chance unfortunately. I know nothing about what's going on with the game, the community, the mods, what I need to change for the voices to work again, whatever.
TLDR; You're gonna either have to find a way to fix it yourself, or just deal with it for now. Sorry guys, but life's taking me elsewhere for the time being. Hope you're OK with that, because I can't really do anything about it right now.
