By the way, regarding Stronghold.
Is it just a visual change to the town or a faction replacement?
Currently, we're talking about the appearance of the adventure map.
That is, the town's interior and the creatures themselves are not affected.
I don't know yet which connections are responsible for displaying the town variations on the adventure map. =)

Since I'm moving some perks from class-specific to general ones, I decided to make the Banshee's Cry look nicer (we see it often in the game, while the Shriek of Horror is seen rarely).
Therefore, I took the Shriek of Horror icon for the Banshee's Cry. And for the Shriek of Horror, I prepared a modified icon, but in a purple color (closer to the dark magic icon).

Unfortunately, I encountered a problem. The icon changed in the spellbook. It also changed in the creature effects. But in the hero screen, in the skills section, the icon is broken, and I don't understand why.
I'm attaching screenshots so you can see what I mean. =)

The funniest thing is that I didn't think there would be problems here. After all, I changed the icon for the Undead Protection against Chaos magic without any problems last month. And now, suddenly, this is happening -_-
