Playing the third node of Challenge of the Courts - Garenbrig, I got hardlocked as three supports kept matching infinitely. I believe it was two Wizard Class supports and know the third was a day/night support. The timeout function didn’t stop the loop.
I’ve attached a picture of the deck , the combat log and a short video clip of the infinite combo.
Video upload failed, so I made a gif instead.
The loop continued for minutes on end.
