Rare candies are considered vitamins, so they should work fine. Also, is grooming added?I'm not sure if a soothe bell is in game yet. Vitamins work just fine and in fact is the reason my Riolu doesn't have 200 Happiness and instead has 216. Rare candies, unless they directly give friendship, shouldn't increase it either. other forms of friendship increasing things should work just fine, like grooming.
