Ever since the Christmas incident I have received the beaver error everyday 90% of the time. Tower, crucible, strikes, I will get into a game for several seconds then get pulled out of the game. The only time I can get anywhere is if I'm piggybacking on with someone else, then I have zero issues. Once I get connected as long as I don't leave and try again I can play for hours. I have an open NAT and as far as I can tell from the guide no other issues since I'm not having this problem with other games. I can join fire teams with out a problem.
