Not sure if this has been reported yet or not, but I've been playing 5.5 and none of my relationships increase or decrease. No matter what I do, they all stay exactly the same throughout the game. I've slept with Vito 5+ times, but our relationship is still at -25. I've given Gossip 3 gifts and we're still at 0. Also, at the beginning when you're supposed to be able to change the fertility settings and relationship status of spouse and Vito, those things never take effect once I start the game. I wonder if this has something to do with the game's persistence? I do have multiple different saves. Is there some way to fix any of these problems?
