Sorry for putting it off for so long I didn't know you could post bugs. I had just hatched a black gondra (can't remember its name) but 2 days later it disappeared is this common and also how do I get it back

Unless it is still in your hatchery unnamed, you don't have a black gondra. You could have sold it, sent it to another user, or auctioned it off but you do not own one now. You can check this out yourself by going to Information, Pet Search, searching All locations for Black Gondra, and setting the order by Pet Owner. Then go to page 46 - it skips from user Dez to user dhim, no Dflower listed.

I never sold or auctioned it you can check the logs i am positive

You do not own a black gondra - unless it is still in your hatchery, unnamed. I'm sorry but you must have made a mistake.
