I have noted something I forgot all the time to mention. When particular players log in the game - it said something like "Player 8" which I believe was Mongolia or Arabia (I have a screenshots so I can check if need be), the game says something like "Player 8 have a different version of files, please check if it is a trusted player".
I think it is not possible to cheat in this game (except for the Oracle bug), but still - maybe even unintentional someone can get advantage or disadvantage by having different files from the others... Dont know if it is important or it is not, but worths the mention. Someone with more experience at modding and game mechanics can explain what this means.
Also, Mongolia, I have army nearby your borders which I can spare and if you want me to, I can help you fight the incoming barbarians.
