There is one very simple and easily applied way to stop COMPLETELY any relationship deteriorating in the game, but it has certain drawbacks as well. Hating the tight caps set on relationships I stopped playing. Definitely no drops in any relationship after that, but no rises either.Is there a way to completely stop relationship from deteriorating?
Oh, after some tinkering I noticed I could for example lift the cap higher or make 'masterlove' rise faster to alleviate 'the problem' a little in case I really wished to. I didn't, so I quit.
