That's unusual, I've never had anyone report that before. Can you please provide more information, if possible? Do you get an error? Does it appear to save, but nothing happens? And what browser do you use? Privacy-focused browsers may need to make cookie exemptions for HTML/Twine games like this.
Opera is a privacy-focused browser. It has default restrictions on the sort of cookies that MERCANOID (and other Twine and HTML games) rely on to function. It would need to be allowed/whitelisted.
