No Errors on loading the game with mod installed and that specific file removed, but I cannot see the new player specialties or slave specialty classes, but I can see the traits like 'stutter, lisp, lactating' and I can see the sizes of vagina/ass/balls etc. only once I'm actually in-game, not in the new game menu.
Edit: So somehow, upon doing the exact same thing I've been doing (with the only difference this time being keeping EVERY window open so I can watch all files get replaced and when) the game is working perfectly? I'll update if anything is broken upon further play.
Edit 2: Trying to use an old save that had partially upgraded the farm, the farm store, snails, and vats are inaccessible. Attempting to rush through a new game and unlock them to see if that is the case there.
