Same here. I got a couple hours in last night then got caterpillar. Sad part, we just upgraded our internet so my internet is now twice as fast as my two friends who seem to never get disconnected. I don't understand, it's like the game is broken in a way that it happens to disconnect from certain peoples' hardware or something, idk what it is but I've spent so much time trying to get a response from bungie and so far, NOTHING!
