Ryze's ult visual bug

Ryze's ult radius was stuck at level 6 radius yet i was level 11. So i basically never knew what the limit and range of my ult was afterwards. in mini map it would show its actual radius but that was still really hard to figure out where exactly the range of my ult was

Edit: ok actually its happening every game now for me... 5th game with ryze and all games had the bug. cant play him till its fixed
