I am also having this problem and cannot unpack or menagerie boxes in the cattery. I unpacked one cat in world and renamed her, but the website doesn't reflect the new name yet and the pedigree link doesn't show up when others click her. If I log on and check her pedigree it still has her old name. Good internet, two computers and had a friend log onto my account from a different country just to check.
Still not working.
Actually no in-world pedigree links are showing up for me, neither my cats or anyone elses.
