tl;dr: I'd like to remove a rivalry between a village cat and a city cat. Not sure how or if I can do that.
So cats that are sent to the city are, as per the warning pop-up, removed from the game. I sent a cat to the city because a) I wanted to poke the unused feature, b) I felt weird about having made their first relationship a rivalry, figured the in-universe explanation would be that he didn't really vibe with my village so he went back home, the relationship would be gone, no problem, no lingering effects.
Thing is, he still has a profile (which is neat, if a little surprising) and the relationship still exists. So now it just feels like the rivalry is strong enough to keep burning within them even if they rarely see each other, which is just weird to me. Is there a way to remove the rivalry so all my not-kitties can move on with their lives, or am I gonna have to make up some in-universe nonsense to justify this?
