May Cat 2018 Gold

[Bellarocks123a]

Not sure if this is just a bug or something, but did anyone else notice that the gold outcome of the cat this May isn't listed on the archive?
This cat:

Who my youngest is 16 days full grown, yet the archive only shows the grey outcome from 18 days.
The gold cat is listed as full grown, so I have no idea why it wouldn't be listed. Did I miss an announcement or something? Full grown means done growing, no surprise changes down the line, right?
Right?
CS?
Pleas?

Hey there;
You're right, the pet is fully grown.
Pets are added to our archive manually by our archivist, so sometimes mistakes happen where pets are accidentally left out.
This is usually fixed quickly, but if the pet still hasn't been added a full week after it grew, feel free to post it on the Archive errors thread :)
