The general rule from Season 1 is that when a game-ending condition occurs, you apply any Legacy effects, but no further in-game effects, and definitely no more player actions (free or otherwise).The Season 1 exception is that if you end the game by curing a disease, any cubes of that disease in the same city as the Medic get cleared, potentially eradicating that disease.
In the absence of an official ruling to the contrary, I'd say you don't have the opportunity to play events (rationed or otherwise) after triggering the end of the game.
