No thumbnails for save-states

[vsub_]

By "save-state loading portion" do you mean when you start the game and press Esc to go to the pause screen(with the menus and the save states)or when you just press F4 to load a save state

The previews are supposed to be visible in the save state manager,in the pause screen and when you are switching between save states by pressing F3.
They are semi transparent when you switch between save states
