Stolen. Just a side note, I usually don't source what I steal because I get concerned that certain individuals stalking these forums will cause trouble to the pages and groups on Facebook that, in the worst case, may prevent them to provide more insider info in future. Of course, that means we won't have any future insight to satisfy our longing to be informed and so-on. Thanks for understanding.
Also keep in mind the circuits of the boss races you see here will probably be randomised for many of us, so you can disregard that.
