Manual Mode: /banishfd 10 and /movefd 10 d b result in an unrepairable game state

YGO Omega Bugs
1
  1. Bug description
    Using /movefd or /banishfd to move cards from deck to banish zone completely breaks a best of 3 duel. The behavior of the FD banish zone after using one of those commands can only be described as “catastrophically broken”.
  • The duel is unable to be reset because 1 card will always be remaining in the FD zone
  • If you have multiple cards in the FD banish zone, returning 1 by 1 to the deck is sometimes successful up until the last card, but only if returning to the bottom of the deck FD, and sometimes the card returned is not the one that was selected to be moved.
  • The last card in the FD zone is immovable. Attempting to move the card provides no error to the user.
  • Logs indicate catastrophic failure.
  1. Bug reproduction steps
  1. Host a game in manual mode and start it with someone (AI is fine)
  2. use either /movefd 10 or /banishfd 10 until you have multiple cards (I did 4) in the banish zone (each attempt will only banish 1 due to a possibly related bug).
  3. Your game is now in a broken state and you can observe the following behaviors of the following actions:

Broken Behavior 1:

  • In the banish zone, click move on card[3] and face down orientation
  • select deck as destination
  • Select “Bottom” and observe a card being sent to deck
    – Open your banish zone and observe that the card previously at card[3] is now card[2] and card[1] is actually the one that was put back.

Broken Behavior 2:

  • In the banish zone, click move on card[2] and face down orientation
  • select deck as destination
  • Select “Top”
    – Observe that nothing happens. No card is sent to deck, and banish zone is still 3 cards.

Broken Behavior 3:

  • Attempt to reset the game state by clicking “Reset”
    – Observe that all but 1 card are put back into the deck, the deck is shuffled, 5 cards are drawn. That last card is immovable regardless of what the player tries to do.
