Auto Attacks stop after using an ability
Have had this happen several times over the past couple of days where I will use an ability and suddenly stop auto attacking (even though attack moving or enemy nearby). For instance, during a game with Vi I would use Q either on an enemy champ or jungle as well as activate E and she would just stop after using it like I had hit "S" to stop every action. It's also happened with Ashe where I I would activate her Q and she would just stop altogether.
