bad code tindust. At least that enemy_flight action.
Better imho:
Code:

---

action enemy_flight
{
	enemy_count += 1;
	my.enemy_number = enemy_count;
	
        while(my.enemy_number)
	{
		// set this entities enemy_number to 0 whenever you want it to die
                // do whatever you want
		wait(1);
	}
        wait(1);
        
        ent_remove(me); //remove it
}
