Gravesight and shifters

I have noticed for sometime, but it's never really matter. However I don't seem to be able to use gravesight to look through the corpse of shifters that die in form. I have tried ever command I can think of. using the shifters form name, their name, quotes. leaving of tings like 'a black' from 'a black panther'. I am sure this is easy to see what I am getting at but I can make up a long if you need it. - Agarah
