It's pretty sad when....
Your immortal vampire has an aspiration to make a lot of friends but you also have mods to increase death reactions, plus another mod which amplifies what your sim already feels.
My vampire was mourning a human friend's passing, and just getting over their death many days later when another friend dies. The thing is, they really only hung out with these sims once, but because of gains to charisma and earning the beloved trait, almost everyone is considered a "friend". And "friends" seem to be dropping like flies all of a sudden.
I guess it's why vampires have the option to dampen emotions. lol. That, or you should never create a good vampire! >:)
