When lag causes a misclick or skipped action. The user isn't disconnected from the client though.

When a player is disconnected during gameplay, and often leads to being dropped from their event.

When the User Experience or User Interface is involved in an issue. Generally not a technical bug, but where the client could be improved to help reduce confusion.

I click on "play with kicker" on Emblazoned Golem, I pay 2 mana and it comes into play with 2 mana in my pool, not allowing me to pay the kicker cost.

Turn 2 in game 1 opponent played muscle burst on a 1/1 and on during resolution the whole game rewound on screen to waiting for dice roll resolution. Now the screen is locked on that and will not go back to where it was.

Raka Santuary does not recognize when you control a blue permanent and a white permanent.

I was playing and Magic Online suddenly crashed and I pressed the buttons in an attempt to get back. It turns out that the game recorded what I pressed and still crashed. When I came back to the game, after reopening Magic Online, he understood that I "pressed" the buttons even with him frozen and that cost me the game.

Ceta Sanctuary does not recognize second state

I face the same bug in standard leagues: if my opponent has casualties of war in their deck, the game becomes incredibly laggy for both players to the point where it's not really playable.

Summary of the problem:

Cruel Reality is expected to have cursed opponent to lose 5 life if they can't sacrifice a planeswalker or creature during their upkeep.

A list of steps that led to the problem:

Used Academy Rector's dies ability to put Cruel Reality into play. Waited until upkeep.

The actual result:

No loss of life

What you expected or should have happened:

Loss of life

The game just skipped the rest of my turn after it drew my card. I didn't auto yield through it or click through it. I lost that match.

When I cast Crux of Fate to kill all creatures Kalitas exiled the Birds of Paradise I owned that they controlled, when Kalitas specifies it only triggers on creatures of my controlling dying. The Zombie Token resulting from this trigger was then able to attack and kill a planeswalker next turn when that zombie shouldn't have been in play

1. Have Ozolith on the Battlefield


2. Have Attacking creatures with +1/+1 counters


3. Opponent casts Aetherspouts


4. Crearures are removed from the battlefield but no counters can be put on Ozolith

Ana Sanctuary's 5/5 effect did not work even with both blue and black permanents on the battlefield.

Simply unable to cast my companion, the card itself isn't showing up and when I click the companion space that my mouse is hovered over in the pic, nothing shows up anywhere.

When Volrath's Shapeshifter takes on a new shape due to the top card in the graveyard being a creature card, it becomes invisible and cannot be used to attack, block or otherwise interact with.

As can be see in the attached chatlog, the etb ability of the creature in the graveyard still triggered (that creatures being Vendilion Clique).

Casting Liquid Fire didn't let me choose a number for its additional cast and defaulted it to 0
