The "attack" icon_state will show up when monsters use normal attack while controlled by the AI, the problem is that this is not the case when you load the mob on yourself.
 
Steps to reproduce:
1. Load a mob on yourself with an icon that has the attack icon_state
2. Use normal attack on something
3. Watch the animation not play
  
Works with AI controlled mobs, just not when you're controlling it yourself.

This should be corrected.
