HoMM3 HD is a mod (add-on) for the game Heroes of Might and Magic 3.

In the original game, the "replay opponent turn" button is unavailable to the player waiting for their turn. However, in HD, it is available on the main screen. When clicked, the waiting player can view their previous turn. The issue is simply the ability to click the button; clicking it always triggers the same function.

I am currently working on fixing/treating the hero duplication issue. As I have learned, there are different types of duplication. I only have examples (save files) of one type of duplication – an invisible hero with an undefined flag on the map (the hero was dismissed or killed). I am interested in what other types of duplication exist. Does an undefined flag ghost ever appear in a boat? Can a duplicate of your own color appear without contact with a castle? Under what circumstances does duplication occur in a castle? Save files of different examples would be VERY helpful.
