Still having problems with shaco's R. This bug is very very old and still not fixed!

I HATE THIS BUG SO MUCH. I always liked shaco's ability to split push with clone. i remember when in old seasons i was used to get inhibs and turrets on my own. Now the clone ( this bug is old as hell but damn riot did not fix it yet) does not autoattack the inhibitor structure. IT SIMPLY STANDS THERE DOING NOTHING AND IT IS VERY TILTING TO A MAIN SHACO.... Not only you nerfed the Q dmg and made the W unstackable, now the champ is not even able to splitpush. I should have just played another champ. That bug just lost me a game. Please help us. We loved old shaco give him back some damage he sucks now.
