Bug Report – Record History Not Working in Rhino 9 WIP

Serengeti (Rhino BETA)

In Rhino 9 WIP (9.0.25217.12305, 2025-08-05), Record History doesn’t seem to work.
Even with history turned on, changing the parents doesn’t update the children.

SelParents and SelChildren still work fine, and if I try to edit the children directly I get the usual “history broken” warning, so the link is there, it’s just not updating.

I know this is a WIP and bugs are normal, just wanted to make sure you know this one exists.

Can you give more details? Which command were you using? Can you post a 3dm file with detailed steps on how to reproduce this?
