GAMEPLAY

Whenever I try to cast my ult as someone such as annie, viktor, ivern, or shaco I can't move my character but I can move my clone with right click. How to recreate the bug- 1.Cast ult 2.Try to move with right click, it wont work for your character but will move your ult. 3.I can get this bug to work 100% of the time. yet I see people play these champs and their ults work fine.
