Malzahar Bot is buying a non-existant item! Cheating Bots Confirmed!

I was playing a Co-Op Intermediate 3's game and noticed I died quickly as a tanky Nasus. I looked at Malzahar Bot's items and noticed that he got a Blackfire Torch (note that it was removed some time ago). Please fix this annoying bug! It is hilarious but it is rather annoying, too.
