[ RHINOCEROS 3D & RHINOGOLD ] Historical Problem/Building Tree

Hi all

I have a small problem with the history/construction tree if you understand me,

For example, currently I'm designing a ring with Rhinoceros&Rhinogold,

I made the gem, then I'm making the kitten/head that holds the gem.

When I want to go back to the kitten/head to make changes, it's not in the building tree!!

BUT, to succeed in getting back to the kitten I built, I have to quit & restart the software and then, HOP, I have the kitten/head icon in the construction tree that I can modify etc ...

I don't understand why it does this to me!

Could you help me or guide me?

Thank you.

Kind regards.
