Bug in Spongify Challenge
This is a bug that I have encountered several times. In the Spongify Challenge, at the top of the room with the ghosts in, there is an Alohomora door. When you go through it, there are green and purple beans and a Fire Crab. DO NOT GO ANYWHERE ELSE APART FROM THE FIRST CORRIDOR WITH THE BEANS. There are two wizard cards and a Challenge Shield, but if you go past the trail of beans there will no longer be an option to exit the room. You will have to reset the console to the last point you saved. This happens to me every time I do this, so WATCH OUT!
