Resetting jungle camps moving wards!!

i first saw this when i was watching one of those random ranked games on the front page. someone had attacked the raptor camp and started to run towards middle lane, bringing the camp with them. there was a ward in the brush right there, and when the camp reset and started to run back to its starting place, it moved the ward placed there to the outside of the bush. i played it back to make sure i saw it right. then afterwards, a friend and i made a customs map to see if it would happen to us, and sure enough, it did. i also tested it with the wolves and it did the same thing. as soon as they start running back to the camp, they will move wards out of the way.
