Today I've been getting a lot of these: Error 523 Ray ID: 1358a1ba3d240400 Origin is unreachable. A couple of minutes ago, I fed my pet Broth a sex berry. When I later went to the page with all my pets, Broth was still listed as a male.

Just pinging you again in case you did not get the ping above. Unfortunately if you fed the berry to your pet, it will not change gender. This is so that gourmands can also get credit for that item. Sorry!
