Timeline inconsistencies
Albus Dumbledore's birth date (1881) is incompatible with that of Adabert Waffling. In chapter two of Harry Potter and the Deathly Hallows, it says that during Dumbledore's school years, Waffling was already an acclaimed magical theoretician. According to his birth year, he was not even born then.
