[HMM II TOURNAMENT OFF] 6th Joint 3-Resource Tournament: "Golden Dragon"

Sorry, but usually in Heroes of Might and Magic II, if there are no opponents, the game simply ends regardless of the victory condition. At least, that's how it works in the scenario "The Clearing." Please excuse my being so meticulous; I just want to understand.
If you really managed to make it so that the game doesn't end until you take the artifact, then I apologize.
