Something that Destiny does NOT do well, that other games handle better, is if you have an Active Download occurring in the background, the game will try to coexist with that download. Other games I usually see a "Download stopped for ....." pop-up when I start playing, but not so with Destiny. Because of this, today I was repeatedly being kicked out of all gameplay, usually with the Baboon or Elk error code. Bungie has the same message for both these codes, that it looks like I have an unstable Internet connection probably because I'm using my cell phone as a hotspot. This was not the case. When I cancelled my download, the game played normally. Hope this helps.
