AI has been very buggy lately
I'm not sure when exactly it started, but around the release of patch 4.18, some of the bots in Player VS AI have been very buggy. This includes running up to players and just standing there, not using their abilities when they would have in the past, and wandering through opposing towers in order to either get somewhere or retreat. This isn't the case for all of the AI, but two champions I can think of in particular are Darius and Alistar.
I know the AI isn't the most important aspect of LoL to a lot of players, but I enjoy it because its a much more relaxing experience, with less pressure and harsh criticism from teammates when you make mistakes. However, these bugs are ruining the experience.
If someone could please take a look at this, I would be very grateful, as, I'm sure, some other players out there would too.
