Noticed today that several card images persisted on the battlefield after being destroyed specifically. Cards would be destroyed by another card, lose their counters but stay in place, with a duplicate card moving to the graveyard or command zone respectively. The bugged remaining card seems to visually have perpetual summoning sickness and other than appearing to be on the battlefield, they dont function or impede normal gameplay.

Also seems like dragging cards with my mouse randomly doesn't work, but all other mouse functions do. This allows me to basically play normally, though without the ability to reorder cards or move cards in scry/surveil.
