To all my french friends, there is a bug where the translation is not working,
So when it want you to say "Hourra !" in the chat it will not work.
I didnt find the key to spell, so my solution for now is to quit the game and change the language of the game in the steam parameters to english and log back in and say "Cheers!"
People do say "Santé !" but it doesnt work.

EN :
In French you have to use in normal chat "Santé !"

FR
En français il faut utiliser dans le tchat normal "Santé !"
