Bots get confused by Ryze's Realm Warp

i was playing a bot game to quickly clear the missions and played Ryze, i was chased by the bots up bot lane, through red side tri-bush, and ulted away. the bots had vision on me and targeted me during the cast and when i teleported they just stood there frozen until a teammate got into their vision, they just stood as we hit with skillshots and didn't respond.
