It says I have over 90 of the character tokens. I've already finished the game so I'm going back into Free Play to get the rest of the gold bricks and character tokens, etc. However, in the Leaky Cauldron when I go to change into another character it only shows that I have Harry, Hermione and Ron. And when I go into the levels I can only choose from those 3. How do I get to the rest that I've already found?
