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

So, it turns out that a third gameplay modification is emerging. The first is the original SoD. The second is HD+ (as bug-free as possible). And the third – sooner or later, it was bound to appear – “at the request of the audience.” Since you’re making a completely bug-free HD+, you should stick to that; everything else belongs in the third, mixed version.
