When you playing the Hunter Subclass, Way of the Wraith, and you successfully make a precision headshot while crouched; Wish Ender doesn't prox Flawless Execution. I believe the Wish Ender's over penetration ability could be the problem. Also when I over penetrate through the first enamy and then get a head shot, while crouched, through the second enamy; Flawless Exacution doesn't activate. Thank you.
