I tried to edit a file in the locale folder. I put locale/en/upgrade.txt in my mod and started editing it. This didn't work. The mod still ran but no messages were changed at all. Do I have to put the entire locale folder and content in my game? Or are we not permitted to change messages? I have changed some upgrade results in the academy and they are not reflected correctly in the message. I tried to change each message and it does not work. I wonder, is there a way to make it work?
