Mine is dropping out as soon as I try to start a mission :(

Same here. Opened every port in my router as suggested with no luck. On a side note, what good is it it to give us all these error codes (lion, fly, groundhog) without telling US what they mean. Hard to take any action on my end if I don't know what to look for. Hey Bungie: tell us if we were dropped for saturation, network loss, ip conflict, closed port, etc!

yep. i got the game a few days ago and i've only been able to play for about 1 hour total. pretty frustrating. i've heard the servers are extremely overpopulated along with the whole sun and solar flare b/s.
