Hello again,
Do you have “AutSave” enabled for prefab mode? (top right of the Unity toolbar). If so, I really recommend against using it (to disable it). When you exit the prefab Unity will ask you to save the prefab anyway. Having it enabled forces the prefab to re-serialize on every change and that can cause a jerky behaviour as you describe. Did the “duplicate name blackboard” error fixed for you after making the change I send you in my previous post?
Let me know.
Thanks!
Gavalakis
