Good game, however
In Prisoner of Azkaban, as professor Lupin I can hit the dementor and tap to cast the spell, however when following the motion of the spell (a simple circle in white) nothing occurs and I am unable to move the game forward. I have looked online and it appears I am missing a level prior to this. I have reloaded the game and tried a different save file. The opening cut scene puts me on to the Hogwarts Express though it should be putting me at Diagon Alley. I tried submitting this glitch to WB via the support link and was told I was unauthorized.
