No emails bouncing back, have just tried other site components and all are sending out emails fine.
I have attached an image of what I see on the details page for an event when 8.2 is installed.
Only other thing I have noticed is the URL's seem a little odd, it is almost as if they are no longer following their original path, but now seem to follow the path to another menu item (which I have set up for frontend access to 'My Events' for event admins).
