After leaving the Zil village and clicking "Go Down" button the game shows "Going Down!" scene, but the interface button doesn't update, it remains as "Go Down" and clicking it repeatedly does nothing, except advances the clock by another 5 minutes.
Oddly enough, clicking on "Main Menu" button (or Save/Load, or Status button) and then "Back" causes the "Go Down" button to change to "Next" like it's supposed to, and allowing the scene to complete.
