[GAMEPLAY] sightstone warding broken

Sightstone warding has been broken for at least 2 patches. After placing the maximum amount of 3 wards and extra charges used, sightstone would indicate you could not place any more wards when you mouse left click on a far away location on the map by making the ward indicator go away. That's to be expected. The broken part is sightstone no longer indicates if you have no more ward charges. If you try placing a ward and you have no more charges, sightstone left mouse click still behaves as if you still a charge when you don't. you waste a lot of time running around warding baron and dragon when you have no more charges. please fix.....
