[AbsolDark]

What type of bug are you reporting? Mechanics

What is the bug?
On broken cup i missed a pulverizing pancake (not z-move) even tho it's labeled as "can't miss" (turn 7)

Chien-Pao used Pulverizing Pancake!
The opposing Sharpedo avoided the attack!

Are you able to replicate it? If so, how?
No

 

[A Cake Wearing A Hat]

Sharpedo was in the middle of using Shadow Force. Z-moves cannot hit Pokemon in a semi-invulnerable state (i.e. in the middle of Dig, Fly, Shadow Force, Dive, etc.).
