It could be due to an “Integer divide by zero” error.

I noticed that both of the properties below are ints.

 public int maxHealth;
 public int healthFallRate;

Does the healthSlider accept ints or floats/doubles etc?

    public Slider healthSlider;

If it is an int like the other two make sure you are not inadvertently ending up with an integer divide by zero situation.
