Platform: PC
Event: Lorwyn Eclipsed Premium Draft

Bug: My first pick in pack 1 of the draft was Mutable Explorer (green rare) selected it, and let the time run out. When the second pack came, the Mutable Explorer became Flock Imposter (white uncommon), and among the cards in the second pick was Flock Imposter as well, positioned in the same place as the previous rare was (topmost left). I ended picking the second Flock Imposter (1st screenshot) but I would have wanted the green rare in my deck since it works much better than a second Flock Imposter. I thought this is just a visual bug like the ones I've seen before but I still have two Flock Imposters even after restarting the client (2nd screenshot). See screenshots provided.

Steps to replicate: Join Premium Draft, then select your pick (I think it must be positioned on the topmost left) and let the time run out. As it moves to the second pick, your first selection becomes a copy of the topmost left card of your second pack.
