Can't move away bug.

Hey everybody.

Lately i have been expiriencing a weird annoying bug which occurs in a lot of my games. Whenever i head into a fight with Jungle monsters, Minions or champions i just can't move away. when i use abbilities or spells like flash to get away my champion will still walk back to the fight. I'm sure that my mouse works and there is nothing wrong with my PC and its equipment.

Thanks for your time.
