RT50 is already out. It's available early at this time of year in preparation for the Christmas Special. Are you looking at the clues for the crossword in that?
When I started doing the RT crossword, the first thing I found was that each year they number them by the corresponding week - so depending what you search for in The Answer Bank, you might well have found clues and answers for Prize Crossword 52 from November 08. Just check the date of the answers :-)
