Same for me. How they could release such ragged event is beyond me.

I don't have the jonin medal and I definitely did all my dailies before 0:00 and it still didn't reset properly. I did however check the login box manually between 0:00 - 5AM. Regardless of that, these things shouldn't even happen. Do they not have any beta testers at all? I consider that a normal and well known practise to check every new event on some closed server to prevent bugs like these from occuring to players. Especially in such a big company.
