Category looping errorEdit

Inevitably if you go up a tree of categories there should be one or more at the top who are not a member of another category... here's one issue I noticed:

• Category:Real world is in this very Category:Harry Potter Wiki. Yet HPW is under Category:Websites (real-world) which is under Category:Media (real-world) which is itself under the Category:Real world so we have a 4-step circle of belongingness. Ty 08:06, April 7, 2010 (UTC)
