You must already know about this what is happening to minecraft? Its being over 6 month and you haven't fixed the buggy AI?

You hit any mob they just stand there.?
You can walk past mobs with no enemy reaction?
All enemy mobs are weak and dumb. (worse AI Ive ever seen in gaming history)

Just a buggy mess. Im requesting you reply back explaining why this has taken you over 6month and theres not being a fix? Even tho you put in your bug reports that you have already fixed the ''mob ai''? You haven't?
