Game had bunch of mods,both sim and ui,before crash I got desynced with everyone else.

See game_14378320.log for more information

Can you provide us game_14378320.log ?

Without a log i can only guess;
A desync only occours when you have different game/mod files than all other players.
Check "all" your mod folders (thera are at least 3) delete all mods, and redownload them.

Thanks for the log.

info: name="Total Mayhem Lite",
info: description="Rebalanced version of Total Mayhem. README in the mod folder contains unit guide and strategic icons fix. Requires original Total Mayhem.",

i guess all other players have the base mod Total Mayhem v1.37 installed ?
Please install Total Mayhem v1.37, its needed for Total Mayhem Lite

Then try again.
