Heres a bug which is exploitable and not banable, but not working as intented.
When you give a love token, the guard is "healed" of a buff using an AURA.
Sometimes, this aura affect another guard and takes its instead.
Female guard to left, male guard to right.
The thing is, you give the token to the female, you "heal" the female by stealing the male guards heart instead - allowing you to token the same guart twice.
Complicated?
1. Female guard steals male guards "heart" through this example.
2. The female is now token'd twice, the male got no heart.
Go on and comfirm.
This saves alot perfume wastes.
P.S dont work always, but it really often works when you are closer to the other guard your not speaking to.
