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

KingUther, that’s a strange situation. Try placing the crimson file in the folder of the selected pack, i.e., in HiRezData\Packs\<pack folder name>
You can find the pack folder name in HiRezData\HiRez.ini, parameter #2

For some reason, the spacebar stopped working in tactical deployment mode. I have to click next.

Oops. A change was accidentally included in the release: the N button now works instead of the spacebar. I will fix it in the next version.

1. The ability to configure road types in the setup - paved, gravel, dirt - for generating a map with such roads.

It is possible to implement this very quickly. But the solution is not direct: the map is generated with random roads, but before the start of the game, all roads are replaced with the one selected in the setup. That is, in random_map_?.h3m, there will be random roads. But when the game starts with the corresponding option selected, the roads will be replaced. The changed roads will be saved. Moreover, the same will happen when launching non-random maps.
Should I do it?
