Ok here we go.
First: 3rd quest chain doesn't appear (I finished the one with the missing reindeers etc, no new one after that).
2nd: The "new adventure" from the calendar I received was 100% identical to the first adventure I received on day 1.
yes I could finish them both (70 presents each) but I doubt they were supposed to be identical and appearantly they also should come with quests which they didn't.
Kinda doubt these things were supposed to happen.
