New mutation of the stun bug in Patch 5.8. Hell, now it bounces back!
Same basic reproduction steps.
1: Have a Dark Sphere from Q. 2: Use Scatter on it into multiple targets. 3: For the most part, works as intended. CC can and will selectively ignore random targets when hitting more than 2. No rhyme or reason.
