Added Order

StatModifier.cs

// Add this variable to the top of the class
public readonly int Order;

// Change the existing constructor to look like this
public StatModifier(float value, StatModType type, int order)
{
    Value = value;
    Type = type;
    Order = order;
}

// Add a new constructor that automatically sets a default Order, in case the user doesn't want to manually define it
public StatModifier(float value, StatModType type) : this(value, type, (int)type) { }
