I noticed that one of my pets wasn't showing up in the hatchery.

I was also unable to click on the link beneath where the pet's image should be. So, I checked both pets that are next to the missing one and got into the page via the Previous/Next Hatchery Pet buttons. The whole page looks like this.

Is this normal? Is the pet going to remain invisible to me even after it becomes an adult?

I see the pet fine. Have you tried hard refreshing the page or clearing your cache? (Just spamming F5 should work though honestly)

Ok! I cleared my cache and then spammed refresh, but it didn't work out until someone had me "Inspect Element". Looked like my browser was blocking it, maybe with AdBlock or something that mistook the image URL for an advertisement or something. Though I don't know why it doesn't block most of the other images if that's the case.

Anyway, I guess it can easily be solved by whitelisting Sylestia. XD

Thanks for looking into it, Krin, even though it's a problem on my side!
