Before, you could only enter a licensed relationship once. If that person disappeared or the relationship ended... well. You were out of luck.
Unlicensed relations were punished a lot harsher as well — you'd be fitted with a collar that repelled all physical contact, regardless of intention. For the first offense it'd be temporary, but if you broke the ban again... well. You'd be prohibited from touching another inmate for the rest of your life.
