After my draw step, my Kumano Faces Kakkazan saga went to the third chapter, went to exile, but didn't come back to the battlefield transformed; instead, a tiny version of it stayed where my exile zone would be. I then tried to play a land, and it stayed hovering over the battlefield where I released it. I then clicked on it, and it greyed out with the "tapped" arrow (but didn't turn diagonally) while still hovering over the battlefield, and the red mana symbol appeared in my mana pool. My opponent conceded at this point (I don't know what they saw), and I took the attached screenshot.
