Cho gath 8/8 stacks ulty

I played a game as chogath and randomly at a point I noticed I had 7 stacks. first thought was wow they changed chogath then I looked at ulty and saw 6/6 stacks max so I was like wtf.... I used ulty on baron and got it to 8/8 stacks. craziest part was even after I died I came back to life 8/8 stacks. I was so confused and just in awe. check my last game played as chogath I lost my score was 4/5/8. just wanted to bring this to your attention.
