Katarina vs. Ryze Bot Glitch
While I was in a Co-op Vs AI match to practice Katarina, I found it incredibly easy to dupe the Ryze bot into walking directly under tower to chase me. I have not tested this while I was playing a different champion, but I have mid-laned against different bots. It did not work against those other bots. I don't know if this is something that started after the Ryze rework, or if it is a glitch at all.
