October 22 Nightmare Duplicate
Thanks for spotting this error. I'm glad that there are others who are keeping track of my Nightmares.
Because I had no access to my Sudoku database due to a computer crash, I could not check the previous entries. In this brief period, 2 duplicates slipped through on the 20th and 22nd October.
I have replaced both puzzles with new originals. You can find them in the archive.
