There is currently a bug with Ashaya, Soul of the Wild and Mythweaver Poq if Poq is the first card played in a turn. This was in Brawl with Slimefoot, Thallid Transplant as my commander on the board. Because Ashaya treats Poq as a land, Poq triggers to duplicate itself, which also triggers Slimefoot because a Forest/Swamp entered the battlefield. Legend rule activates, I have to sacrifice one of the Poqs. When I do, Poq triggers again, which also triggers Slimefoot again, causing an unintended infinite loop that keeps going regardless of which Poq I sacrifice for the Legend rule.

This kept going even when my timer went to zero, infinite looping by itself without my input. I had zero control over it. It got to the point where I had at least 50 Mythweaver Poqs in my graveyard and about 40 triggers on the stack before my opponent surrendered.

When in this infinite loop, I was also unable to concede the game myself.
