Important! Must-Read! Enderman bugs!

I've seen a thread on the Minecraft Forums, saying that a few mobs have been broken, and Endermen are the worst. They have the following issues:

1. Endermen, after teleporting, path-find their way back to the space they were at before teleporting. (Noticed when an Enderman teleports, but teleports back into the same spot a second later.)
2. They stop getting angry at the player after losing sight.
3. Does not get angry that often when getting looked at.
4. They walk too fast in a glitchy way.
