Immortality Changes

Inspired by The Sims 3, this mod changes the aging and immortality of Vampires and Werewolves.
Starting from Young Adult:

Vampires will age 5x slower (still unable to die of Old Age);
Werewolves will age 1.5x slower.

Like TS3, you can buy a reward trait to stop Vampires from aging again. To keep symmetry, I also changed the Immortal Wolf trait so they can now die of other things (except Old Age, since they don't age). As a consequence, both Pack Leaders are now unable to die, to prevent game-breaking issues.

WARNING If you use MC Command Center:

MC Occult will override any aging changes, so you must manually change in the settings. Do exactly as below:

Vampires:
MC Occult > Vampires > Age Setting > Max Aging > Elder
MC Occult > Vampires > Age Setting > Multiplier > 500 (for YA+ and older)
Werewolves:
MC Occult > Werewolves > Age Setting > Multiplier > 150 (for YA+ and older)

You can also delete this package and use only MC Occult if you don't care about the immortal traits!

Manipulate Life Spirit Override

Drinking from living Sims — with permision or not — can restore a bit of your Vampire's age. And if you have the Manipulate Life Spirit perk, you'll be able to control the effects of time itself.

Drain Life Spirit will now age down your Sim. As for the victim... have you heard of a Death-Flower-Scented Bouquet? 😉
Restore Life Spirit will have the opposite effect, but the cost isn't that high for you (and none, if you're immortal). Night creatures "live" longer, after all.
Both interactions will have consequences in your relationships and reputation.
