Favorited around 300 designs for custom products on spreadshirt the other day.
Logged back in today with zero favorites, so that is fine I just went through and favorited 1609 designs today, well immediately they are already being deleted and are now down to 1400.
A little bonus for all of this is by logging in on another browser or just logging out on my current browser, it will for some reason reset all of my favorited designs so that the list is completely empty like a brand new account.
