I think I broke it a little, playing around with INT64_MAX - https://mathstick.github.io/play?q=hrojihaacciabcmtskiistbij...

Edit: mostly directed at OP, the puzzle maker claimed something like 12 identical solutions for the same puzzle

Fix the integer overflow issue. Now your share link will only the first puzzle, the other two puzzles are invalid thus won't be shown any more. If you don't see any changes, you may need to refresh the browser to see the latest version.

Yeah, you did! It's integer overflow, good catch!
