Hsbg 'sleeping sea glass' freeze

After I play sleeping sea glass and try to choose between doubling atk or health, all of a sudden it doesn’t show the image and text of the card and deactivate everything including playing other cards, leveling, freezing, refreshing, or anything else except ESC key and surrender or Quit Hearthstone. And just like the post made right before this, HS is now no longer reconnecting to my current game, so it’s hiliarious that I’ve lost about 3-4 games just because of this sleeping sea glass freeze bug.
It’s so darn disappointing when I spend my 30-40 min to win the 1st place of a game, and choose one random wrong minion card just to make that win meaningless. I’m a Korean user and hearthstone is infamous as ‘the worst indie game of blizzard’. Hope you guys can fix this bug and restore my hsbg points asap.
