I viewed both logs and did not saw any issues. A desync means you have different or modified files that don't match with others players. Validate your game files with steam. (again) 2a. Delete everything inside C:\ProgramData\FAForever\gamedata\ 2b. Host a game with the FAF client to redownload the files into \FAForever\gamedata\ Delete all mods, also *.SCD mods that can be located in any \gamedata\ folder (kyros lobby as example) 4a. Delete the game.prefs file located in C:\Users\YOURNAME\AppData\Local\Gas Powered Games\Supreme Commander Forged Alliance\Game.prefs 4b. Start a game via Steam and create a new player inside the game (needed after deleting game.prefs) Then try again.
