Looks like I've been hit by this bug. Typical that it's in the same family that always gives me the most grief... Anyway they're both full relationship, the status get's to extremely irresistible and I don't even get the option to become boyfriend/girlfriend. I've tried moving them out and back in, I've moved him in, I've killed them and resurrected them, I've sent them to a foreign nation and still nothing. They've both had previous romantic interests but have 'asked to be just friends' with both of the Ex-Interests. Has anyone fixed this bug or is it still unfixable?
