Intermediate AI Bugged champs

I have played a few Bot games recently and I've noticed that a few are bugged, most notably Jhin. For some reason he just decides to go AFK a few minutes in and never comes back. Another bot that did this was Yasuo. There was also a Fizz that would just walk to lane and eventually die to minions if we didn't kill him quick enough. Ironically, each time these bugs occurred we also had a bot on our side doing their jungle thing. So in a way it was balanced [slayer-jinx-unamused]
