What issue of Dungeon magazine did 1st Edition material switch to 2nd Edition? Roughly issue 18?

I have an original printing of I6 Ravenloft.  It has a strange problem or typo/mistake.  The Key Numbers on the Wilderness map do not match the reference #s in the module.   I always thought that it was funny but I didn't think much about it till I received in the mail my RPG version of I6 Ravenloft (Silver Anniversary edition) which fixed the problem.  Also when I purchased the Silver Anniversary Collector's Edition and read the re-release of I6 Ravenloft I notice that the problem was fixed there.  You make no mention of the problem in any of the I6 Ravenloft desriptions.  Has there ever been any mention of it?  I wonder if TSR caught the problem would they have done a second printing with a correction? It's seems to me that it might have been important enough for another printing.  Have you heard anything about this?

I was trying to determine which printing of Q1 Queen of the Demonweb Pits I have (1st or 2nd).  I looked the item up under the modules section but I didn't quite have enough information.  My copy looks like the lighter purple but seems to have all of the legends.  Where exactly are the legends missing?  From the inside cover or the cardstock map insert?  Or possibly from one of the module pages?  Any help would be appreciated.

I was looking through B2 Keep on the Borderlands to run for a few friends recently, the copy I have on hand is from the Silver Anniversary box edition.  One strange thing I found was the names of the NPCs were written in the indentions of the book.  I though this was pretty strange because the names are not printed type but it looks like someones handwriting.

Example, page 8 has the name Oleg (entry yard), Arthur(bailiffs tower), Andrei, and Galina(jewel merchant).  From what I can tell blocks of white adhesive were used (similiar to whiteout) and then the names written.  I'm just curious if this is a standard thing for the Silver Edition of B2 or I just have a weird copy.  I didn't see anything about it listed on your page.  Anyhow, the module is pretty much straight out of the box so I know it has not been tampered with.  I'm the only one who has had access to it and it was new.
