Since the March 22 2023 update the old moon black rust hunter daily now requires me to kill five black rusts to complete not 5 small ones 5 large ones 

I've deleted and reaccepted the quest multiply times aswell as reset my Xbox several times, sailed back n forth to rusts and every time it's kill the full grown rust x5 killing the young ones does not advance the quest only killing the large 

please look into it since it's kinda a required quest and killing 5 rusts for one tear is a bit much when yesterday it was 1-1 

Greetings!
