JOverseer is writing my orders in a non-English language

Multi-language support is incomplete. JOverseer will assume the orders are submitted in the same language as the computer it is running on. If you want to override this, start joverseer with the command line option (without quotes) ‘-L EN’ which means use Locale English. The translation information lives in https://github.com/JOverseer/joverseer/tree/master/joverseerjar/resources/ui as message_xx.properties, where xx is the ISO code for the locale.
