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

No, I recently played a game (less than a week ago) and had to load the autosave twice. Now I loaded it in single-player – the issue is gone. In Hotseat, they forced me to fight manually. In multiplayer, they definitely didn't let me skip the battle. The game started on September 26th.
