Missing strings from translation data

[genjo97]

Posting this according to last discussion on Discord.

There are some interface strings that I cannot translate ("Terrain Feature Range", "User Save Location" etc + their descriptions), I assume they would be either in gamedata.po or main.po but unfortunately these and some others are missing. I opened FCS, opened my translation there and exported the lines according to guides, but it didn't help - FCS spits out the files 1:1 to my older copies everytime.
