Oh I feel all your pain, but I believe I have figured out how to fix the beagle error (no thanks to bungie or microsoft). I've completed all the Venus missions now (previously I was getting the same issue on the 1st Venus mission). When you download the game content to install, it's about 15GB, however there is also a smaller 'update' that needs to be installed of size around 15MB (I think from memory). The timing of when each of these components is installed is VERY important. The key here is not to 'open' destiny until the game has installed at 100%, do NOT open destiny after about 2% (when xbox1 tells you it is ready) as when you open the game, you'll be forced to install the update at that time (when less than 100% of destiny installation progress). I think there's some issue applying the update before the game has been installed. Therefore here is your happy path; 1. Delete installation of Destiny 2. Install Destiny; DO NOT OPEN THE GAME BEFORE FULLY INSTALLED AT 100%. Stay on the xbox1 menu. 3. Open destiny once the game has fully installed, you'll be prompted for the smaller update. 4. Enjoy visiting Venus!

Only way I managed to get the game working was to join a Fireteam that were doing the [spoiler]moon[/spoiler] missions. Then I unlocked the crucible for PvP and the next planet. Must say the game is amazing it's definately worth t
