I've been putting some pico-8 games up on a personal website since it gets past an annoying block list, but I've noticed something strange. The games with highscores that save via cart data sometimes get reset back to their original states with none of the highscores. I checked in the developer menu and saw that cart data was being saved to local storage in the browser. I'm wondering if this is a known issue, hopefully with a known solution, or if there's something I'm doing without realizing it that's causing the data to be reset.
Thanks

in theory local storage is fine and persistent until people delete it, but some browsers may be weird and delete data some time after the last visit to the site.
