Routing

Has anyone experienced strange Routing? it isnt as smooth as it was, for Example. Jungling as shaco, usually he will be far enough for the blade of his Dagger to hit a creep. However recently since last patch clicking on a creep will make you walk towards it. Same happened to a Miss Fortune on one of my games. She clicked Gromp and her Champion walked infront of gromp instead of attacking this. This is a big issue because it is effecting champions aswell. Sometimes you click a champion and your champion will go to where the click was instead of following that champion.
