@Jip a pity, i wanted to save the element of surprise. Thnaks for a response.

When I tried hosting a game of world domination and every game hosted - crashed, which was a real bummer since many people wasted an hour of their time in lobby sim. So I tested and narrowed the problem - once you set spawn to random - unbalanced and teams - manual select, with rnough players in the lobby (you can just add bots to all spots) the game wont start and lobby dies. this has caused much more butthurt that i'd like to admit but hopefully writing this ticket eases my pain.

As in title, every time I launch FAF client it adds #russian to the auto-join list, creating useless #russian chat tab
I remove from the chat settings but is reappears every time. How do I stop this?

The problem was in the hardware. Repasting the GPU stopped any crashes on 4k.

Thanks for heads up! I will be sure to report with as much info as I can if we pin down the problem.

We haven't experienced any desyncs in 3 games now. BTW, can screen resolution and UI scale cause problems in-game? Because other that desyncs, sometimes his screen just goes black and whole PC reboots. That is a different matter though we speculate it is because he has 4k screen. as if he lowers the resolution, game works fine.

It cannot be a map issue as it happens on all maps as long as RazerRunner is a player. He is doing a steam verifications right now. I will write back on the result.

We both have Steam version. The logs I gave are RazorRunner's - the person having issues. I am attaching the same game log file from my side: game_22714335.log

Right after starting the game, my friend causes a desync in a whole lobby. it happens every second game strangely, the second half being played without said issue, and we cannot find why. We reinstalled FA and FAF, but the issue persists. I attached log files, ice-adapter.log and game_22714335.log and you can see this happening in replays, for example: https://replay.faforever.com/22714335 If anyone could tell the reason for desyncs and how to fix them? I would gladly give more info if needed. Thanks!
