I found your explanation pretty pretty useful in order to “solve” some jigsaw puzzle caches. Only a few days ago it was working perfectly for me, but today I cannot find the release.js file in the debugger any more, even after logging out and in again to Jigidi and reloading the puzzle several times. Therefore I also was not able to set a breakpoint correctly and skip shuffling.
Did Jigidi again change their code? Or am I just to blind to find the right line?
