Intermediate Annie Bot in Twisted Treeline using Blackfire Torch

Me and my friends were playing around on some Twisted Treeline Co-op vs AI, and the enemy team had an Annie Bot. I don't remember when, because I didn't take notice of it until a bit later into the game, but the enemy Annie had purchased...Blackfire Torch ... The item similiar to DFG on Twisted Treeline that was apparently removed. We were wondering why she had unreal burst and now we know. The strangest part is that... human players can't purchase this item. It doesn't show up in the item sets list or shop list. This Annie bot bought a nonexistent item. I'm linking my match history (I hope it works) where you can see a whole in her inventory. Well, they all had full build at the end of the match. That whole is where Blackfire Torch was. It was just really strange and interesting and I think it should be addressed at some point.

I'll also give you the link to the "Removed items" sections to prove this item shouldn't exist.
