Question about some translations in this lesson

Bonjour Melody ! Actually in this case, I agree that "Nothing happened/arrived" would be a more common translation. However, you could also use "Nothing has happened", as Le Passé Composé overlaps both Present Perfect and Simple Past. If you said "Rien n'arrive", it would mean either "Nothing happens/arrives" or "Nothing is happening/arriving". You can also have a look at this lesson: https://french.kwiziq.com/revision/grammar/how-you-use-depuis-since-for-with-le-present-and-not-le-passe-compose-prepositions-of-time I hope that's helpful ! Bonne Année !
