First picked "Darling of the Masses", it changed to a blue card (Can't remember the name) after I picked it. I assumed I misclicked. Once I built my deck, I wasn't able to submit it because of a "Network Error". Went back to the deck builder and the card was back. Re-building the deck I think there were a couple other cards that changed after I picked them. This really screws with the draft and I saw it happen on LSVs stream too.
