I adopted ......Saphira..... from the adoption centre but now this appears bellow her on my pets page : ! This pet's name may break features across the site. You may file a ticket for a free name change or more info.

Is this just because of the temporary gold account or something else?

They are offering a free name change but do they come up with it or do I have to do that?

I would imagine it's like any other name change, and you can pick whatever name you like as long as it's available.

Also you aren't strictly required to change the pet's name, it's just an option for a free one since it may cause some coding issues. But you're also allowed to just leave it alone if you don't care.

I had it too, you can come up with a name (or snag an available one)

I was lucky and was able to get it changed to Lady Saphira, which I think is better.
