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.

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

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

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.

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.

I was playing AFR sealed league, R2. Score was 1-1 and we started 3rd game when we both had like 9-10 min on timer. During 3rd game i got hard lagging what results in losing by timer.

mid game it restarted, after the restart the game is just skipping through turns going immediately to discard

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.

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

Play Lobby Disconnection/Dropped

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

1. It is night and Leeching Lurker is on the battlefield
2. Cast 2 spells on your turn so it becomes day next turn(search party captain and curse of leeches)
3. Neither player has hexproof/shroud etc.
4. Actual: Upon Leeching Lurker's transformation it goes to the graveyard
5. Expected: I am given the choice to attach Curse of Leeches to target player, and the enchantment remains in play.

I was playing when he played a card of Strixhaven (Expressive Iteration). Game broke. I saw all the game again since t1, like when you review a past game on Game Historial. Then the game restarted

The game kept reseting and replaying the entire game up until the point of the bug.

At the beginning of game two after i played my first land Shelldock Isle and was resolving the Hideaway trigger the game startet again. My Opponent and i both got a new hand of seven cards.
Each turn after that the client went directly to the cleanup step and made us discard a card due to maximum hand size.

Cast Wedding announcement in MTGO sealed and mtgo immediately crashed. It crashed 2 more times on reopening. The weird thing is it clearly crashed my opponents client as well, because they ended up timing out and gave me the win.

Spoke to some other players and it happened to another player with wedding announcement as well. Note I successfully used the card before so I'm not sure exactly what caused it, but it was played turn 3 this time.
