GUID not generating automatically

[BurritoBushido]

Installed manually from package.

I have a prefab with a class inheriting GUID. Guids are never generated automatically. Context menu functions work. Prefab instances never generate new guids either, they inherit whatever is in the field for the prefab asset.

I'm also having this issue, when instantiating prefabs in-game or duplicating prefab instances in-editor.

Currently, it seems GUIDs are only auto-generated for pre-existing scene instances. They aren't auto-generated for dynamically instanced prefabs in-game (i.e.: GameObject.Instantiate(); dragging a prefab to the Scene View), or for duplicated prefab instances in-editor (i.e.: Ctrl+D).
