Hello guys, today I played a match as Rakan against a Braum in botlane. He was placing his wards into the bush at the river without being in range. I tought he was hacking but after I tried to do the same in a custom game with my friends I found out it was a exploit/bug. If you stand at the wall and place a ward on the stone off map it lands in the bush. I think this is a game breaking bug which gives players that know about it a huge advantage. I put screenshots on the link so you can see what I'm talking about.
