Had the same issue, reached mythic in limited and the draft I was in the middle of became locked in place. In hopes that it was just the draft I resigned, losing all progress and the opportunity for additional rewards, but after beginning a new draft came to find that I was still locked in place. One thing that I have been experiencing that I haven't seen mentioned is that my daily quest progress is not being fulfilled either.
