Bug Found with the sideboard in the deck editor for MtGA.
I found an interesting bug when I was deckbuilding with my sister. We both found that whenever we would try and move cards from the bottom or top of the sideboard and swap them with another card, we would visually clone a bunch of the card that was in the center. In our example, my sister found that whenever she would drag any card from the bottom to the top, she would create a bunch of copies of Eidolon of the Great Revels visually. If she tabbed out, everything would be fine though. If she did it from the top to the bottom moving a Tormod's Crypt with a Surgical Extraction, she would only create a few visual copies of Eidolon of the Great Revel. It's not a particularly harmful bug from a visual perspective but it would also prevent her from permanently moving a card from the top to the bottom.
