Lol, it used to be that way, now its as they describe. You pretty much have to purposely stop doing anything else and start him on purpose. Last two updates I struggled more often starting him or restarting him than what you describe.
Hey, I hate the mode itself regardless of how often or easy it starts. Yet another poorly thought out never ending mode.
But it's a two-ball multiball, with a chance at add-a-ball. Not like it's some epic huge Wizard mode that's out of place or something.
Pretty sure RH is too caught up in how it used to be, and not how it is currently.
