[GAMEPLAY] Attack Move on Cursor not working when bound to left mouse click

This is a bug that has causing a lot of losses for me. With normal attackmove, whatever is closest to your cursor is what your champion attacks. However, I have attack move bound to left click for better orbwalking. Problem is, though, that attack move on cursor doesn't work with that bind. I nearly got a triple kill in my last game, but teemo put a shroom right next to me, to which i attacked instead of the enemy team. This bug has costed me countless games because I have to either A: have to hope no minions or obstructions are closer that whomever I'm attacking when I attack move, or B: click back and forth, which, due to my lower-than-average framerate, is very inconsistent.

Here is the guide I used to bind attack move to LMB: https://www.reddit.com/r/leagueoflegends/comments/1bo2nk/guide_to_easy_kiting_left_click_attack/

When bound, you'll attack move when you left click. But, unfortunately, it does not work with AM on cursor.

Hope to get feedback soon! I'm on quite a losing streak because of this bug.
