In the main lobby (in the hut), I opened the menu and clicked on "quit game", but instead of quitting, it launched a race
I realized later (after killing the game from the computer), that I was facing the board, and maybe it has priority over the menu.
So maybe I was pointing at a race, through the menu, and instead of selecting the "quit game" button (which was highlighted though), it selected the race
So it would probably be interesting to give priority to the menu when it is open, so that doesn’t happen
