At least in russian language a big bug, everywhere is not "Классические шашки" it means Standard draughts, everywhere it is written "Классические шахматы" it means Standard chess. Maybe it not only in russian.

Thanks for reporting, I'll change that! So "Классические шахматы" should be "Классические шашки"?

We used the lichess translations, and tried to remove everything chess-related (but clearly failed here), so that most of the menu's and options are translated.

We were hoping to setup a Crowdin project for that, so people can help with the translations more easily, but unfortunately that would require an expensive paid package due to the amount of sentences lidraughts contains.

Yes "Классические шахматы" should be "Классические шашки". Thanks for fixing it.
