[GAMEPLAY] The "Attack move on cursor" option does not function consistently in game.

The game-play option "Attack move on cursor" does not function in a consistent manner and will operate as if it is not enabled on some auto-attacks. The champions auto-attacks will frequently NOT be directed towards the target nearest to the cursor when you order an attack-move command but will instead be directed towards the target nearest the champion.

To reproduce:

1. Open the "Options" menu
2. Select the "Game" tab
3. Enable "Attack move on cursor"
4. Attack-move near a minion that is further away from the champion than another minion. The champion will frequently attack the minion closer to the champion instead of the champion closer to the cursor.

I have reproduced this bug in all attempts to reproduce. The bug does not occur on every auto-attack but occurs very often. It does not seem to be affected by champion choice, occurring with Draven, Caitlyn, Lucian, Ashe, and Jinx. It does not appear to be affected by Summoner Spells, masteries or items as well.

Link includes images of the bug with attack moves being declared on the far side of an enemy minion wave but the champions attacking nearer minions.
