Okay, so I've been trying to walk my way through coding my pet pages, with tons of help from this forum (thank you everyone who has written up guides and tutorials and provided code to jump off of!).

I thought I was getting the hang of it, hitting 'Preview Profile' throughout my editing. So I finally saved it, and then went to 'View Profile' instead... and it's completely different. My pet's treasure is now missing, as well as the description text. Is the preview seriously broken??

Have you tried checking the Problems and Bugs board or filing a ticket? This seems to be more of a functionality issue than a coding issue. Or did you use square brackets in your code? Because square brackets don't work on pet profiles because the sCode compiler looks for them.
