Can you post you game log or even better post it in the #technical-help channel in the FAF Discord
I’ve seen this issue before. Can’t remember exactly what the cause and solution was off the top of my head. I would guess missing or corrupted textures tho. Did you try rehosting a few times?
Did you try joining a game to see what happens? Welcome to FAF btw. I too am a recent vanilla convert and it's way better over here.
Let there be light
*C:\ProgramData\FAForever\gamedata* check this path, are there .nx2 files?
Well, I can't seem to be able to find ProgramData \ FAForever, I only have "Program Files" and a "Downlord's FAF Client" folder which does not have the .nx2 files (nor a gamedata folder). Even the non faf's supreme commander files don't have those.
Nevermind? I somehow fixed the game? I literally have no idea how the hell have I done that. I've just turned off the client, played a bit of total war napoleon, opened the client again and boom - the UI works and the game is fine now..
What the hell?
