Sometimes, when minions are shuffled into your deck by opponent, you cannot see the cards that you draw and the game is completely broken unless you restart the client.
I don’t understand why this HUGE bug isn’t fixed yet, there are tons of report of this.
The Psychic Scream issue is well known and affects all (?) effects which shuffle cards in opponent’s deck. See:
If you encounter again an issue which prevents you from playing, you can force-quit Hearthstone (Alt+F4 in Windows) and restart it right away to return to the game in progress. This should clear the invisible cards from effects like Psychic Scream (though future draws might still have the same problem).
Well that “fix” is not really a fix, I play 99% from mobile and force closing the app and restarting it usually take quite some time and when the game reconnects I lost 3/4 of the turn and rope is starting or already half way, so I can easily lose a turn and consequently the game.
Same thing just happened to me. Tried to log out and in… but it took too long and I lost. Hucking Fell.
Indeed, this is not a fix. This is a workaround which can possibly change a sure loss to a more fair fight. I wish Blizzard comes with the actual fix soon, since that is quite a disruptive bug.
