When I start the game, I'll get an xbox message saying "Looks like you own this", followed by another xbox message saying "You already own Expansion II (sometimes it says Expansion I)". After this, the game itself shows a loading screen for about 2 seconds before I get an error code: Boar. I've tried hard resetting and deleting and reinstalling both expansions to no avail. Additional info: I game share but the game + licences were bought on my xbox and account. I recommend trying Fix 2 before Fix 1. Fix 1: It IS game share that is causing this issue. Disable it by setting your xbox as the "home console" (Google it if you cannot find it). Fix 2: So I tried game sharing again and this crap appeared. This time, I closed Destiny, deleted both CoO and Warmind. Then I started Destiny again without redownloading the expansions. Had no problems thereafter.
