Marie, That was not a 'glitch' if you have used a content management system of any sort you would understand that, You need to check changes into the system and then someone with the right credentials needs to push your changes to production in a corporate environment these are NOT the same people. So while it was an error it both the pricing and credit allocations were based on REAL data in Disney's Content Management System.
Now they could have been 'pushed' as a trial balloon to see how people would react i.e. 'Accidentally on Purpose', But this is not some 'random' error this was a deliberate action on Disney's part.
