Yeah, ?-4 was a pain. I was thankful to get it out of the way early (ish) on, so I could relax and just farm Life Crystals from the event without worrying about getting all three medals. Oddly enough, I've managed a full clear more than a few times since, so it probably would have came to me naturally even without my stressing over it. Even still, I hate having something like that looming over me. >_<
