BFH was looking into this, and found major design issues with the bushies. I will have another look at it but the main problem was storing data in the session and changing session.
Ideally when there is no flash the main page should degrade nicely and not throw hundreds of errors. Such error report: http://magicduel.invisionzone.com/topic/15974-erro-ajax-bugs/
Yeah so this is a problem with how the consuming works and im not 100% sure if there is/isnt a problem here. I will try and look into this issue in the next week.
