[GAMEPLAY] Orianna Q ball permanent ward

As Orianna i was able to place the ball into the bush using her Q skill, leave it in the bush, and walk away until it automatically returns to you. After it returned however, sometimes the bush would still be lit up. I'm not sure whether the map just shows it being lit or if it actually acts as a permanent ward. I noticed after 1 placement my original game, and about 3 or 4 times in the last game i was testing. It worked in both river bushes nearest midlane, the second bush on the right hand side of the river, and the ancient golems on blue team's jungle.

I don't remember the original game I was playing when i found it but I just tested again and reproduced the bug. Both were normal games on Summoner's rift. My last particular game was a custom game with 3 other bots, 2vs2.

1. Clicked Play Game
2. I hosted the game.
3. Was on the blue team
4. Entered Champion Selection page
5. Selected Orianna
6. Game Launch
7. Launch ball into bush Q.
8. Walk away and let it return to you automatically.

and like I said, i was able to make it happen anywhere from 1-4 times of launching it and having it sent back.

I submitted this as a request and a player support person said they reproduced it as well.
