@uveso It hink this is workaround not solution. I can fix my own mods but I cannot fix other players mods. Checksum check needs to be at faf itself. Also all versions needs to have own name so game it self cannot think that two version of same mod are same.

It think it would be good to add mod version number to each mod name and put faf client to check checksum of mod folder lua files before each game. That will enforce that all players must have perfectly same version of mod. Currently specially total mayhem is total pain to get same version for all players.
