GAMEPLAY - Bot Item Bug in Twisted Treeline

I encountered this bug today while playing bots in twisted treeline. Both Malz bot and Nid bot ended up grabbing blackfire torches and using them during the later part of the game. I double checked the store to make sure they hadn't magically shown back up, but as the screenshot shows, the bots were using them.

to reproduce: play Malzahar Intermediate Bot on Twisted Treeline and observe item purchases.
