While playing survival Minecraft on my iPhone, I've noticed that multiple entities in the game seem to have broken path-finding (zombies, creepers, skeletons, etc.) 

Expected Result: 

Hostile entities will attack you in a straight line (head-on).

Actual Result: 

Hostile entities will approach you in a zigzag form (move left and right).

How to reproduce:

1. Spawn a hostile mob near you in creative mode, then approach the mob in survival mode. 
2. Notice how the mob moves in a zigzag pattern.
