Persuasion skill Lvl 2 +3 do not work

[Lionsmith]

Hello all

I have the Gold edition from Kings Bounty Armored of Princess.

This includes the expansion set "Crossworlds"

So I played Crossworlds "Orcs on the march" as a paladin.

As I upgraded my persuasion skill from Level 1 to Level 2 nothing

changes. So I didn't get the morale boost +1! Level 3 is the same.

I have mostly humans (knights, paladins etc) in the army

If I click on the unit to look on the morale values

it tells me only +1 Morale skill:persuasion. So nothing changed when I

upgraded the skill persuasion from Level 1 to 2 and 3. So only Level 1

is working correctly. Does anybody have the same problem and is there

a solution to fix this?

Cheers
