I've tried all available translations in the mod, but in the end the mod doesn't want to follow the locale settings in the game and uses English.

This is being worked on: #70

At the moment I'm working on other things but once I get enough time I'm going to circle back and try to finish it up and get it merged. If you know how to use git/the commandline to clone and run ./gradlew runClient, testing would be helpful, but if not then I'll get it done myself eventually.

Implemented localisation in 1.0.8, however you still need to restart your client to apply it

There is also an issue even with completed translations where languages will not reload until a client restart
