My oldest son purchased the Expansion II, House of Wolves add-on in Destiny for his gamer profile on our youngest son's Xbox One. We then purchased our older son his own Xbox One. When he signs in to his gamer profile on his new Xbox One, the House of Wolves add-on shows that it must be repurchased. Does the add-on have to be repurchased or is there a way to reinstall it to his gamer profile on his new Xbox One? Thank you for your help!
