About changes and/or combining Hero Specializations.

lol, I guess I'm stuck in 2016. Back then, there was a separate patcher for maps.

"As I understand it, this program is in an executable file, and a set of maps is run through it. If you need to add heroes from NHF to your map, you just need to add it to the executable" - this was more of a question from my side than a statement. I played a standard map with NHF relatively recently, maybe two months ago, and it was enough to just run the correct executable. At least the standard maps were included, while fan-made maps probably need to be run through it, but I didn't find this utility in the package. I don't know, maybe I didn't pay attention, and it was somewhere in the mod archive.
