I got my first Throdama (http://beastkeeper.com/pet/141840) and noticed that, er, he lacks the bone genes. 

Those are listed in the gene library, so I'm wondering if that's a bug (pun not intended)...or if only some morphs get those genes? 

Thanks for reporting!

Throdamas do not have bone genes because they do not have bones just like normal insects. So yes, this is a glitch that they had bone genes in library. It's fixed now.
