Hello, a friend of mine start playing this season, and he started as a hunter played the beginning bit, artifact, done, got the season pass started on wish all the best on his hunter, but then he decides he wants to switch to Titan. So he does and he does the beginning bits, get artifact, can talk to Queen Mara, but he can't to Riven and can't find "Wishing all the best". How would one fix this problem?
