Unentwine component

Hello,

I have this component but my colleague doest not.
I have Rhino 8.16, he has 8.15. Is it something new to SR16? I’m about 95% certain I first used it in SR15.
I’ve found nothing in my special folders. I also tried Grasshopper Addons & Plugins | Grasshopper Docs and haven’t found anything. Any idea where is it from?

Do you have the Treesloth plug-in downloaded?

No, I have these.

Is it a userobject?
