Kled's W and R bug

Kled's W sometimes cancels early, losses the attack speed bonus before the time expires and sometimes 3rd hit has the final hits animation, R doesnt follow the pats it shows, example: i ulted from 2nd midlane tower to mid inhibitor and kled didnt follow the path and went around toplane, another buggy example is i ulted from bush near raptors to the little bush in the river, kled went around dragon pit, stoped mušiau, turned around and went the way it should
