I'm the one who arranged this pack. I did include updated menu graphics for all languages since I had the opportunity to do so. I have only heard about save corruption from those who attempted to merge their vanilla save with NT, but I am curious to hear about this vanishing Vincent bug, where have you heard that? As far as exe edits, we are trying to avoid that as much as we can, until we cant.
Well not only Vincent vanished.... He turned up in the north crater and you wont believe this but he was called Sephiroth in deafult make of that what you will but i have finished the game.
