Bug Loss of node reference with instance of a prefab that use embed graph

I have a lot of problems with my current workflow with VisualScripting that is extremely frustrating.

I have a prefab that contains an embed StateMachine.
I edit the graph of this StateMachine in the prefab without any issues.
However when I use an instance of this prefab in a scene I always need to revert the change to update the graph (even If I revert the object the override remains).
And I also often have broken references on some random nodes in the instance of the prefab (making a modification and revert it again will often correct the problem).



This page shows that it "used" to not be supported but it is on an older version (1.6) https://docs.unity3d.com/Packages/com.unity.visualscripting@1.6/manual/vs-prefabs.html and there is no mention of this in a newer version (at least I don't find it in the 1.8 documentation)

Has anyone else experienced this problem? What are the possible workarounds for this issue?
