[Please do not change your game Language to Thai until further instructions.]
 

If you encounter this error please delete the “Nation.ini” file located in your local
FS2 game folder, the file will then be re-download when you launch the game
and the language will be reset to default (English).

for anyone who was inconvenienced by it please accept our sincerest apologies.
