I have completed this game although only at 40% and now going through in freeplay. I am now looking for dark magic and when I go to my character list it doesnt show the ones I have acquired??? Therefore I cannot choose another character and am stuck. I keep going back to the leaky caudron to try and purchase the characters in diagon alley but it just takes me back to hogwarts castle and I am lost here. Have no idea how to move along in the game. Hope someone can give me some tips!!
