Zac Crash Bug

Zac Crash Bug.

Ive got that problem that whenever i use my E on zac i have a chance of crashing. Because of that bug i Crash around 6 times per game. This only happens when i play zac and when i use my E. This happend several games now and I hope to see it fixed soon. My friend got the same problem. But like i said it doesnt happens every time. I just have a small chance of crashing when i use it. And it can really be game changing.
