Have to clarify myself, I downloaded the ENG version from the russian site, and my Mate did it from the French mirror, same file name LO_Flaming_Cliffs_Patch_1[1].12a_EngWEB.exe
and after he patched his game (fresh install of everything) with it we could no longer play with eachother, he only could see a join button as spectator, no in blue or red side.
After he reinstalled and DL it from the russian server, we can now play.
So I say it's confirmed.
