3's Bots still buy atmas impaler? [GAMEPLAY]

So, about a week ago, my friends and I were trying to get good at 3's, so we played a bot game with intermediate bots (Irelia, Malphite, and don't recall the last one) and at end game, 2 of the 3 bots had purchased atmas impaler. Unfortunately I did not take a screenshot of this when it happened. I do know this isn't a a huge bug, but just wanted to make it known.
