Or just something to look out for.  The Austrian Hunyadi class CH has two versions represented in the book.  The version in the actual fleet section, complete with an illustration, has the ship as a 19-hit hull.  The version shown in the scenario-specific ship displays at the back of the book (the sheets you can xerox when playing a battle) is a 24-hit hull version.  The ship went through a lot of revision when the glitches in the ship building spreadsheet were first discovered, and it looks like two variations made it into print.  Both are legal.  The 19-hit hull one is the one I prefer, however, since 24 just seems too big to qualify as a "heavy cruiser."  It's more like a BB.  But since both are legal, I guess it's up to folks which they would rather use.
