In the Witch Academy the stairs to the basement on the left crash the game with the error: "Uncaught SyntaxError: Unexpected token in JSON at position 39843". Looked into the .json "Map364.json" that threw the error: "parameters":["you helped out it' s only fair you get to"]. Between the ' and the s is the not supported character "\u0009" aka tab key. Simply delet it and you're good to go.
