I think the issue would be that Ravenloft is a module/setting/whathaveyou which is, if not currently IN print in some form, only recently OUT of print and will undoubtedly reappear in print in some form. Most recently I think there is a castle Ravenloft board game and before that it was probably the Expedition to Castle Ravenloft hardcover in 2006. To make full, accurate CC maps of Castle Ravenloft available publicly would almost certainly be trodding on toes best left untrod.

I have my own CC maps of Ravenloft (fairly simplistic) but only ever made an unkeyed .png of the ground floor map available on my own website. I've made a lot of maps of cities from Judges Guild's Wilderlands settings that have been up on my website for a long time, but then they've generally been years, even decades out of print in any form.
