Idk if anyone else has this minor thing, but when I get a card pack, all the cards are... reversed. If I click on one, it goes gray while the flipping animation is happening until the actual face is supposed to be visible. And when I junk one, it similarly flips back, but stops being gray and shows the reversed card instead.
Also: this started a few days/weeks BEFORE season 3 packs started dropping.
EDIT: Here's the looks of it.
Top left: Freshly clicked for the first time.
Top right: Clicked, then junked, then clicked again.
Bottom left: Freshly junked.
Bottom right: Not yet clicked.
