This puzzle is based on a collaboration puzzle by 15 authors. At some point it was my turn. I added a killer cage somewhere, attempting to create some interesting logic, but it turned out that this cage imploded the puzzle to only 2 solutions, without creating much of a solve path. Completely astonished by this, I had to figure out why. I can't say that I found a satisfactory answer, but this research did lead to a puzzle that I think is interesting enough to publish. All this does mean that the list of rules is longer than usual:

Hope you will enjoy!
The break-in is the same as in the original puzzle. Because of this, I thought it appropriate to credit all original authors, regardless of whether or not their clue survived.
See https://f-puzzles.com/?id=yxk93l2d for the original puzzle.
Solution code: Row 7 and column 3. I.e. the 9 digits in row 7 from left to right, followed by the 9 digits in column 3 from top to bottom, for example: 123456789123456789

The puzzle wasn't hard, but it was incredibly fun and satisfying to solve! Every deduction made my day better. :)

This has been one of my favourites so far. Loved the flow, I was constantly making new deductions instead of getting very stuck at one particular point - yet it did not feel easy at all. Thanks!

Beautiful puzzle, every logic and deduction feels so important, which makes the puzzle go smoothly. I enjoy it very much, and congrats everyone for making a nice puzzle.
(I haven't done the original one yet but I'll take time)
*Extra* The original one is also very beautiful too, definitely a gem for my favorite sudoku collection. Both of the puzzles took me like half an hour for each of them, but I enjoyed every second of the ride.
