Before I tell what's going on, let me I put a video with the source code.

**EnemyHealth**
var startingHealth : int = 100; // The amount of health the enemy starts the game with.
var currentHealth : int; // The current health the enemy has.
var sinkSpeed : float = 2.5f; // The speed at which the enemy sinks through the floor when dead.
var scoreValue : int = 10; // The amount added to the player's score when the enemy dies.
var deathClip : AudioClip; // The sound to play when the enemy dies.
var enemy : GameObject;
var playerHealth : PlayerHealth;
private var anim : Animator; // Reference to the animator.
private var enemyAudio : AudioSource; // Reference to the audio source.

private var capsuleCollider : CapsuleCollider; // Reference to the capsule collider.
private var isDead : boolean; // Whether the enemy is dead.
private var isSinking : boolean; // Whether the enemy has started sinking through the floor.
function Awake ()
{
// Setting up the references.
anim = GetComponent (Animator);

// Setting the current health when the enemy first spawns.
currentHealth = startingHealth;
}
function Update ()
{
// If the enemy should be sinking...
if(isSinking)
{
// ... move the enemy down by the sinkSpeed per second.
transform.Translate (-Vector3.up * sinkSpeed * Time.deltaTime);
}
}
public function TakeDamage (amount : int, hitPoint : Vector3)

// ... no need to take damage so exit the function.
return;

// Reduce the current health by the amount of damage sustained.
currentHealth -= amount;
// Set the position of the particle system to where the hit was sustained.
hitParticles.transform.position = hitPoint;
// And play the particles.

// If the current health is less than or equal to zero...

}
}
function Death ()

// Turn the collider into a trigger so shots can pass through it.

}
public function StartSinking ()

GetComponent (NavMeshAgent).enabled = false;
// Find the rigidbody component and make it kinematic (since we use Translate to sink the enemy).
GetComponent (Rigidbody).isKinematic = true;
// The enemy should no sink.

// Increase the score by the enemy's score value.

}
function Spawn (){
// If the player has no health left...
if(playerHealth.currentHealth <= 0f)

return;
}
Instantiate (enemy, transform.position, transform.rotation);
Instantiate (enemy, transform.position, transform.rotation);
}

**EnemyMovement**

So yes, I'm learning a little bit of tutorials on unity - those about here http://unity3d.com/learn/tutorials/projects/survival-shooter - and something is going wrong, that i can't fix. In this film you can see it clearly, points are awarded properly but the problem is with the nav agent. The aim of such an arrangement script [in the original spawns are done in a separate component] is the simple fact that after the mob death, in circle of his place pops up two more on the animation 'birth' [in the simplest short, these beets pop out of the ground :)]. Well, I do not know how to fix these errors and I'm not a programmer - if anyone can help? [translated with little help from g.translate :) ]
