When I spawned an enderman in creative, the first thing he does is pick up a block. Then he walks toward the water and hits the water ant teleports. Then when he teleports, he walks toward the water again! His AI is not even playable within the game. Please fix!
BUILD 2
I can confirm this still exists in build 3, and with a naturally spawned enderman.
He tried a dozen different angles (almost 180 degrees max separation) to walk into the middle of this pond, taking damage each time.
