The current pre-release of the client ("pioneer" in the version) is only compatible to itself. So you can only play with other testers. Please be aware!
@stoprudnov To change language in the FAF client:
click hamburger button at top-left (explanation for what is a hamburger button: https://en.wikipedia.org/wiki/Hamburger_button)
click "Settings"
click "Language"
select Russian
To change language in the game itself:
while the game is running, click the circle button at the top of the screen
click "Options"
click "Interface"
click "Language"
select "RU"
User rights got super crazed, prevented me from changing them (even as an admin).
Removed entire FAF folder, reinstalled the client, restarted PC and the problem got resolved.
Thanks!
For testing purpose, disable any security software/firewall. I would guess the firewall is interfering with the patched files, when it has worked before.
I think it is flag of Cyprus? Not sure about that, hard to see in the image.
