The problem is that he is desyncing in almost every game for months now. Everytime when someone in the game gets even a smallest spike/lag/fps drop or anything like that, its almost guarantee that this will cause desync between my buddy and at least one of the players. Usually between 2-3 people. The game stops and wont start unless he leave.
Mods are not the issue because the problem is still occuring even on the fresh system and faf install after ground format. He is playing mostly vanilla faf.
The logs im posting were taken before recent messy faf updates and before he made a clear format so they contain some mods. I can tell him to enable logs now on the fresh system if necessary but the issue is identical so i dont think it will make any difference.

For the lazy ones: game.log contains thousands of these:
