I used OpenTTD on PortableApps platform. My PC environment is Windows 10 Pro x64.
OpenTTD's language setting was not saved correctly. When I restart OpenTTD, language setting are changed to English. Other options are saved and loaded correctly. Only language setting has problem.
I tried to manually edit openttd.cfg but not worked.
It should change automatically to match the language of the platform like most of our apps
Sometimes, the impossible can become possible, if you're awesome!
