Azir- Auto Attack bug.
This is a bug that i don't necessarily know the trigger for because it happened to me in a game then after I went into a custom to test the bug and it was fine. Despite this however during the game it was giving me trouble Azir when using attack move (and sometimes just normal AA's) would walk in the direction of the click after preforming one auto attack, making for some very hard to control movement. Like i said i don't necessarily know the trigger but i thought i should say something.
