Hello,

It sounds like you may need some more troubleshooting advice, please submit at https://mtgarena-support.wizards.com/hc/en-us/requests/new and select 'Technical Troubleshooting'.

Thanks!

Sparky keeps saying "Hmmm." without taking any other action and the game does not progress due to it. This has gone on for several minutes.

It is the end step of my turn, I have a Kasmina and a wizard token, Sparky only has 5 untapped Mountains. My guess is that Sparky is trying to cast Command the Storm on my wizard, but cannot do that due to Kasmina's static ability, which makes the spell cost 7 mana instead of 5.

Edit: After submitting, I conceded the game. This lead to a Command the Storm going on to the stack from Sparky's hand, during the animation of my avatar exploding. This further supports my guess.

Yup, seems like sparky keeps getting dumber and dumber (or smarter depending on how you look at it because the only way to get out of this is to concede).

I too have confused sparky, green/white deck vs black deck. just used mark of the multitudes to get ten tokens tapping everything on my board and i have no cards in hand. sparky has four cards and no idea what to do, lol

Same issue here as others have said

Similar issue with sparky during a bot match. She was down to 2 health on her turn 9. I was using the pre-constructed white blue deck and she was using the red goblin deck. Has three cards in hand and next turn would be my win with 4 creatures ready to attack against her one.
Stuck saying Hmmm... I left it on at least 10 min without a decision made from AI. After conceding the game, it showed "Command of the Storm" trying to cast with her 6 red mana open.

I'm also stuck in the "hmmn" loop. See attached jpg for board state. Honestly, I've been playing since the closed beta, and in that time I've only posted twice on the forums, and both of those were suggestions rather than problems. Since the M20 update I've experienced 2 game-stopping issues (sparky Hmmn and gameplay freezing during a Sealed game) and the whole game has failed to load/find the server more times than I can count. What the heck is going on with this update?

It was Sparky's turn and I had Teferi's emblem out, and randomly during her turn she just wouldn't go at all. When I conceded, it then showed the spell she was casting(attempting to cast?).

annoying

I experienced a similar loop with Sparky.

I went first and played a land.
Sparky played a land, forest, then passed to me.
I played a second land then Lazitop Reaver.

On Sparky's following turn Sparky drew to 8 cards but did not play a land, then Sparky began to emote the Hmmm... emote over and over.

The game is stuck in this loop with Sparky saying "Hmmm." over and over.

My guess is that Sparky does not have a land to play and can not play any spells and will have to discard a card at the end of turn. Somewhere in the decision process, Sparky gets caught in a loop.

I had the same issue. It only occurred after I was ahead really bad.

Had the same problem

Similar lock, but had Kasmina in play if that affected anything. Was able to concede.

Same problem, here's mine:

Here's my log, but I can concede.

I attacked sparky and Sparky just kept saying "hmmm" and not deciding blockers. didnt do anything and just sat there in "hmmm" forever

Attacked sparky during training for lethal damage. Sparky is now stuck in a loop saying 'hmmm' over and over. Presumably shes thinking of casting an interrupt, but has nothing in hand.
Cannot skip turn
Cannot concede
Cannot exit game
