Problem Modding Armored Princess

[zipy]

First of all, hello to everyone I am a new user here,

Now to the topic. Because Armored Princess forum don't have mod section, I had to post it here.

I changed some values in hero.txt and logic.txt, but only some of them work.
I added one spell for warrior, but it won't appear in the game. At the same time, when I changed warrior haste scroll into learned spell, it was working in the game. I also changed some attributes for mage, like added one point intelligence, and it isn't working either.

I added same leadership gain per level for mage, that warrior is having, but it was working only in beginning. When I loaded game, it wasn't working anymore

In logic.txt, I tried to tweak starting gold for normal difficulty- won't work either.
I tried also changing a bit logic_hero.lua file, to get difficulty changed- again nothing happens.

So, for now, I'm little bit confused

I'm using russian version of the game, what is translated more or less into english(found translated loc_ses.kfs file from armored princess forum)

Any help or pointers are most welcome
