Somehow, the article 'Castlevanis DS' ended up being listed 5 times in each of
its categories.  (See Category:Castlevania_games and Category:Nintendo_DS_games)
 After removing the category tags only reduced the counts by 1 each, I reverted
the category deletions.  I could find no duplicates in the page source nor any
redirect pages.  Even if this is a one-time error, there should probably be a
logic check for duplicate records in a category at the point of member deletion.
