Failed to add '[...]' to language 'french': language does not exist.

[Pythagorion]

Everytime the server boots, this error is printed to the console ('[...]' = the classes that does not support french).

I guess we can add a conversion thingy here. However the language identifiers are incorrectly named because it is fr instead of french. There are warnings for the devs of these classes so that they know they should change it

[Pythagorion]

yes. It doesn't stop us from playing either, as we all play in English or German. In the long run, however, it can be annoying when programming, for example, as it clutters up the error menu, but that is more of a comfort issue than a real handicap.
