I'm sorry if this isn't the right place to post this, but I think I found an untranslated bit of dialogue. If you Ctrl+F for "par jour" in the first script file, it'll take you right to it. It's in the section for buying the home catering service for "jname".

Don't be sorry! This is highly possible indeed. The translations are made through a patcher kindly developed by Dingotush for the overall game to be understandable to non-French speakers while the game is still in development, and the patcher may miss a few strings. I won't deal with translation issues before the release of a stable version, since it would mean retranslating many parts every time an update comes up. Thanks for taking the time to report the issue though! And thanks for playing the game :) Cheers!
