I was going to win game3, no doubt, and the game suddenly crashed. I wasn't able to rejoin in time, and lost th egame. There is no reason for the game to crash like that, since I'm always playing and that never happend.

Play Lobby Disconnection/Dropped

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.

draft begins and draft window close reload magic online but lose several first picks

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.

1.Activate mindslaver targeting opponent
2. During that players turn, cast their lightning helix while holding the control key
3. Actual: priority immediately passes to non active player, no opportunity to have active player(opponent being controlled) respond to their own spells
4. Expected: Active player would maintain priority, would be able to make them respond with their own daze targeting their own helix

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 there is either an error message, or the client is unresponsive, and you must force close the client.

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.

If I take more than five seconds to do an action in my main phase it will skip to the end of the turn.

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.

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.

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.
