Okay. So I bought House of Wolves on Xbox One, but apparently it doesn't carry back over to Xbox 360? Now how am I supposed to play with my last gen friends? Also, I was able to play House of Wolves DLC earlier today on both consoles, but now I can only play it on Xbox One. Also, I just learned that if I had bought it on 360 first, this wouldn't be an issue. Somebody help...
