Ошибка компоновщика: LNK2019 генерируется в статически связанном проекте

Итак, моя команда пыталась реализовать собственную реализацию shared_ptr, чтобы мы могли снова успешно протестировать наш игровой проект в режиме отладки (VS2013). Тем не менее, мы сталкиваемся со следующим списком ошибок

Основная проблема, с которой мы сейчас беспокоимся, это LNK2019 для оператора bool в классе Handle. Для справки, вот класс в полном объеме:

template <class TYPE>
class Handle;

template <class TYPE_TO_CAST_TO, class TYPE_TO_CAST_FROM>
Handle<TYPE_TO_CAST_TO> static_handle_cast(Handle<TYPE_TO_CAST_FROM> const& subject);

template <class TYPE>
class Handle : public HandleRegistrar
{
  // friend all Handles so that we may convert them
  template<class U> friend class Handle;
  template<class T, class U> friend Handle<T> static_handle_cast(Handle<U> const& subject);

  private:
    bool m_weak;
    int* m_ref_count;
    TYPE** m_ptr;

  public:
    void destruct(void);
    int use_count(void) const;
    bool expired(void) const;
    void swap(Handle<TYPE>& rhs);
    TYPE* get(void);
    TYPE* get(void) const;
    template<typename TYPE2> Handle<TYPE>& operator=(const Handle<TYPE2>& rhs);
    Handle<TYPE>& operator=(const Handle<TYPE>& rhs);
    template<typename TYPE2> Handle<TYPE>& operator=(TYPE2* rhs);
    TYPE* operator->(void);
    TYPE* operator->(void) const;
    TYPE& operator*(void);
    TYPE& operator*(void) const;
    bool operator==(const Handle<TYPE>& rhs);
    void operator%(Handle<TYPE>& rhs);
    operator bool(void) const;

  public:
    ~Handle(void);
    Handle(const Handle<TYPE>& rhs, bool weak = false);
    template<typename TYPE2> Handle(const Handle<TYPE2>& rhs, bool weak = false);
    Handle(TYPE& object_to_point_at, bool weak = false);
    Handle(TYPE*&& pointer_to_object, bool weak = false);
    Handle(void);
 };

У нас нет никакой реализации в файлах.cpp для класса Handle, он полностью реализован в заголовке. Я некоторое время искал решение этой проблемы и просмотрел так много статей LNK2019 о SO, надеясь найти что-нибудь об этой проблеме... Любая помощь или понимание того, что может произойти, ценится. В нашем игровом проекте много чего происходит, поэтому, если потребуется дополнительная информация, я ее предоставлю.

Вещи о проекте:
-Статически связанный код распространяется по 11 библиотекам.
-Предкомпилированные заголовки используются.
