Cannot mod AP after CW installed

[magister]

Here another example.
A camera mod as you everybody knows, is worked very well on each campaign when it's in /session/orcs(or champion, defender)/mods, but do not work on origianl AP whether it's in /session/addon/mods nor /data/mods. I put it in every directory under Kings Bounty Armored Princess but it didn't.
It only worked when I replace it an orginal file(/session/addon/ses.kfs/camera.txt)

And here another example too.
I made an translation mod for non-english user, and there's very strange thing.
It worked fine when there's no additional camapaign(in other words, eng_windows.lng is woked good), but when I add an new campaign under /session(like item_pack) they did not work correctly(eng_orcs(or champion, defender)_txt.lng aren't worked). Instead they show the original file in each kfs file. It worked only when I replace original file, too

I wonder how mods work. I thinked it worked very well when I just put new file in sub directory in TL and AP. But in CW, they didn't I think

Please let me know the way it work fine, except replacing original file.

ps. I'm sorry but I'm not an english user, so please pardon my very poor english
