[GAMEPLAY BUG] Darius e (pull) turns off AA targeting

Bug occurred on twisted treeline, have not tested in summoners rift. Occurred consistently in two separate games, one on the 25/6 and the second on the 26/6.

Whenever I use Darius' 'e' (pull) I can no longer target my auto attacks properly. I have to left click to 'reset the cursor' to a normal targeting one (the hand), instead of an attack cursor (red sword). Bug continues indefinitely until cursor is 'reset' by left clicking, it almost appears to be like the reverse of attack move, as i can right click to move but not attack. It makes targeting people straight away after using the pull very difficult. For example, when I pulled an enemy champion and right clicked to attack them I would instead move to their location and attack whatever was closest at the time, which was often a nearby minion.

Additional information: I use smartcast for all of my spells and I do not use the attack-move command, I only right click to move/target.

I look forward to a quick response from Riot, as I recently received the Dunkmaster Darius skin as a mystery gift and would very much like to continue playing him! NosNos
