I've seen this bug before, but I wanted to confirm that it wasn't just a "one time thing" before I made a post here in the forum about it.
Basically, the Taric Bot is badly glitched. He worked normally in the beggining of the match, but I entered the bush next to the middle of the towers and poked him a little bit. After that, I came back to lane and noticed that he wasn't showing up, so I decided to go back to the last spot I saw him and this was happening:
Hope u guys can fix it soon, it's kind of difficult to get kills from a bot that stays in the same far away spot, even if he was walking in a very easy pattern.
