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

If the template author intended for there to be two-way connections between zones, but the generator creates one-way connections (and this happens not because of the author's intention, but simply because the generator doesn't have enough two-way connections for complex templates), then this is a distortion of the map, i.e., a bug, and the author of the HD mod strives to eliminate bugs. Why the adherents of the sacred generator, who didn't defend other bugs (which have already been fixed), have latched onto this one is not very clear to me.
