When playing the midweek magic Cascade Brawl every time I play the planeswalker Quintorius Kand after the automatic cascade effect takes place the planeswalker card remains in the area designated for the stack and any other card I try to play after also freezes in the stack or in the case of a land mid air over the battlefield. The glitch goes away if Kand is removed from the battlefield but returns again if I play him again.
