weird cursor bug

was playing an ARAM earlier and i wasnt able to directly click on any enemies. The cursor was either always a finger, or always a sword and when i tried to click someone it would simply move my champion to that location and, if they attacked me, they would be auto attacked by my champ. I found that dying or moving items around in my inventory reset this temporarily, however, each time it was short lived and it seemed to always break again right when we started to fight. Making me all but worthless.
