I've never used the cider debugger/cider in general, but let me know if you find out what the problem is--I'd be happy to update biff if there's a way to fix it on that end.

I will! Thanks Jacob 🙂

Is it possible that the functions get reloaded after the debugger has set the symbols (I don't know how the debugger works)? There is an auto-reload feature on save of the file.

That’s a good place to investigate, thanks for that! Will look into it today 🤞:skin-tone-3:

In any way I think reload-on-save beats the debugger completely as you can just connect to production REPL and reload your expressions directly there with the erroneous state in place.
