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

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

While drafting, lag causes a user to miss a pick or timeout from the draft.

For when there is client confusion or an issue that can not be reproduced or attributed elsewhere.

When a player is unable to submit their sideboard due, often giving an error message, and often for having having 14 or 16 cards in their constructed sideboard, or other various issues during sideboarding that aren't transitioning issues or the client crashing/becoming unresponsive.

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.

For when an issue occurs when going to or from sideboarding back to the duel scene.

Play Lobby Disconnection/Dropped

When my opponent cast distant memories on me it gave me no option whether to put the card in their hand forcing me to concede to end the game without fully conceding the match.

I've been playing vintage cube last week and I've been met with an annoying problem. Sometimes when I pass priority or want to click OK, the client lags but my timer goes down. This usually takes 20-30 seconds before going on. It happens several times in a match which can cost me up to 4-5 minutes of my clock.

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.

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.

On MTGO online, there are cards that are not working in standard. Narset's Reversal, Lutri the Spellchaser, and Expansion. I play an instant or sorcery but it's not letting me copy the spell. It only let's me copy if an ability triggers first then i can add it to the stack. But it should let me copy it right after I cast the spell. Please fix these issues as these cards are worth playing in tournament. I've tested it time and time again. Please respond back when you have time.

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

When using Slimy Kavu, it turned my Opponents land into an island, not a swamp

Necra Sanctuary trigger abillity doesn't work properly.
When it triggers, and i have a white permanent and a green permanent, my opponent loses only 1 life, but he should have lost 3 life instead. Even if i have a multicolored permanent, that have both colors, green and white, it still doesn't work properly.
I try to build a deck around this card, but i can't play with the deck properly because of this problem,

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.
