Cards drawn from your deck put there by Psychic Scream are invisible in your hand and can't be played

Heard a few reports on this but I was waiting for more information.

Encountered a bug in wild not long ago. At the start of my turn with two cards in hand, I drew an “invisible” card that could not be played and did not add to my hand size. After emptying my hand, on the next turn I drew another “invisible” card, and could not attack with my minions. The end turn button still showed “enemy turn” though I got a rope and my hero emoted as if it were my turn. Afterward, my opponent was able to take turns as normal while I was still locked out of the game (ruling out connection issues).

Seems straightforward enough, but this person in that thread experienced the same issue with Marei Loom:

I got an invisible card bug too, but instead of Wild, I was doing Chapter 1 of The Dalaran Heist. All cards I’d draw were invisible, and by turn 3, I was no longer able to play any cards, even the ones I’d started the game with that I could still see. REALLY nasty bug!

The issue doesn't seem reported nearly widely enough to be as simple as affecting any cards shuffled into the deck, as otherwise the Marei case would be affecting an enormous number of players. The two cases do seem related, but it's not clear what triggered it in the lone Marei case. Platform appears to be PC, history bar doesn't show anything out of the ordinary, and it seems to be the first boss so no Passives would be in play. The only thing that comes to mind is that perhaps a transforming Unidentified Contract was somehow involved, the only card in the starter Rogue deck that could do a strange thing to a card without being played first.

Another similar Marei case - here it seems to have occured alongside (or caused) a client hang: https://us.forums.blizzard.com/en/hearthstone/t/dalaran-heist-heroic-bug/7621

Playing against Marei. On her finished turn 2, she hit the end turn button, but it stayed on Enemy Turn. I gained my 3/3 mana but I am unable to make moves or continue the game.

In normal adventure against Archmage Kalec, i have Dr. Morrigan on board and no cards left in the deck He kills my Dr. Morrigan, that goes in the empty deck https://i.imgur.com/7BhrV1f.png

My turn starts, the draw animation triggers, my other cards in hands shift to the left, but Dr. Morrigan is not in my hand https://i.imgur.com/tKg1p02.png

So i’m a fairly new player, and i just claimed Frozen Throne single player mode from the shop. It works fine until the Turn 3 of the second battle. I can’t play any card (no highlight) and it seems like there are 2 invisible card on my hand.

Lots of reports of it affecting the Icecrown prologue. Seemed like it was only affecting cards moved to the deck from other zones, but I would expect those to be created in the deck. Worth checking a log to be sure.

This bug happened to me twice while playing as warlock the first time on Android and Priest the second time on PC. Both times the bug occurred were when I had a full board of minions and my opponent uses Psychic Scream.

Partial fix this patch. Hopefully full fix next patch.

This issue is actually resolved in this patch. Sorry it wasn't included in the patch notes!

Note that we were only able to get a partial fix in for this release, so you might see a little visual weirdness when this happens (but no more invisible cards). Expect that weirdness to be cleaned up with the Saviors of Uldum patch.

possible fix?

Fixed an issue that could occasionally cause freezes and disconnects after Psychic Scream was played.
