So I just installed Stainless Steel for the first time and I started the Hungarian campaign. When I entered a battle I noticed that most of the units are black, with some weird heraldry I cannot place. The flags that float above the units are the same as well.
Is this meant to be or is this some kind of a bug? The generals and standard bearers wear red and green tunics with the right heraldry.

They look like this in my game:


Shouldn't they look more like this?
