I see the dialogue font has been added as well already. Many thanks. I tested it
and works perfectly.
Moreover, the language change does not require game restart now anymore.

I saw some translation issues with CZ active (mix of languages):
1) If you open Contribute in menu, the content (text) is in English, not in CZ
2) The same is valid for Credits
3) The same is valid for game beginning (scrolling text before game begins)
4) In game - Skill help window (skill description when clicking on "?" in
Skills) is in English
5) In game - Skill names are in French language
6) In game - the dialog window where player choose dialog sentences as the
answers - if dialogue is ongoing, there is "Click anywhere to continue". I
didn't find this sentence in the translation so it is not translated at all
probably.

Last but not least, I would like to update the translation because I did some
corrections based on game review. 
Is it something I can do directly or I need to send request to you each time?

Thank you
