NHF – new heroes for Heroes V 3.1.

this is a unique bug related to the "Favored by the Gods" specialization – for some reason, it provides a link to the Furious.xdb file, which contains the paths to the icon and description of the "Aura of Speed." Therefore, we need to understand where the link to the file responsible for displaying the specialization buff is defined (Furious.xdb is responsible for displaying the buff applied to the unit from the "Aura of Speed" specialization).

So, the specializations themselves work correctly (from a mechanics perspective), but for some reason, both specializations refer to the same file, "Furious.xdb." In the hero's file, you can specify individual paths to the icon, description, and name of the specialization, but this concerns the display in the hero's window, not in the unit status window during combat (as shown in the screenshot).
