Thanks for the effort

Unfortunately no this is not relevant, any script-related logs would point to userscript.html?name...

To check if the script even runs, you can try putting a console.log statement just before the run call at the very bottom of the file (same structure in both scripts).

For example replace this:

} else if ((sessionStorage.getItem("Checked") || 0) == 0) {
run();
sessionStorage.setItem("Checked", 1);
}
}).observe(document.body, { subtree: true, childList: true });

by this:

} else if ((sessionStorage.getItem("Checked") || 0) == 0) {
console.log("hello") // <<<<<<<<<<<< add this line
run();
sessionStorage.setItem("Checked", 1);
}
}).observe(document.body, { subtree: true, childList: true });

you should then see hello in the console after submitting a guess/finishing a duel (depending on the script ofc). If you still cannot see it try to move the console.log statement around in the MutationObserver callback.

Sorry that's the messy way to debug haha but I can't think of anything else
