Infinite loading after adding Gishki Aquamirror to a deck

  1. Bug description
    After adding more than one copy of the card “Gishki Aquamirror” to a deck, if I save, exit and then open the deck again, the game gets stuck on a loading screen and I am forced to close it. I’m not sure if there are other cards which cause this bug but it’s the only one I found so far.

  2. Bug reproduction steps
    It’s easier to show with a small clip: YGO Omega Gishki Aquamirror glitched - YouTube

  4. Expected behavior
    I should have been able to edit the deck normally after adding the 3 copies of Gishki Aquamirror
