Exactly what AmericanCrime said: "AN essential Bloodlines patch/mod. It fixes almost everything inherently wrong with the vanilla game and aims to enhance the experience as well by restoring content. Highly Recommended!!!!!" This is the TRUE patch for any loyal fan of the game. There is absolutely no reason to not use this patch over any other patch, that claims to be, 'official'. All the mods for the game, use this patch as their foundation & regularly update to work alongside this masterpiece…
