[GAMEPLAY] Xin Zhao CRIT STRIKE Bug

I was playing Xin Zhao in a normals game and noticed that his Crit Strike would jump from 0% (no items) to 100% every other attack, making every other attack always Crit. I had no items at the time and when a Crit item was bought it would just go from 20% ( for example) to 100% instead. I hope this gets fixed soon.
