Same thing has been happening to me. Error codes HAWK CATERPILLAR and CENTIPEDE. This is only when destiny allows me to see an error code. More likely than not it just kicks me to the home screen and disconnects me from Xbox live so there is no error code in the message, just a snarky remark about needing to be connected to Xbox live. And all this happens just after I spent an additional $35 just to get that damned speeder a little bit sooner. Hands down the most frustrating thing this game has done so far..
