Changing Language doesnt revert all strings, such as nationality or weekdays.

Also Staff jobtitles and media description of players haven't changed.

There are two language options now - one for game language and one for data language so you need to ensure both are set as desired in the beta

We've changed the logic of this for the release version so that on start up it will change both game language and data language if you choose a language that is different to the locale of your computer
