RoM - REAL Potion of Rejuvenation! (Patreon)

Yup. The stupid potion will now actually age down your sim... or age them up, if it fails. 

Careful: it can bring you down to child.

I'm not sure children can drink it, but if they can, it will reset their age progression on success.

For elders, it will fill the progression on failure.

Mod idea of Jaqueline Vatore.
