Deadened Emotions and Undead Aura - not good for making friends

Hi! sorry, I know this is a really old post but I had used a Master Vampire base sim, But they had Deadened emotions and now I can't get rid of it, I've made the drink, even resetted using cheats but nothing has removed the buff, I've been searching everywhere and this has became my last resort, because he's just set to "fine" all the time it's hard for him to do anything that needs other emotions from the game.. Please help?
