ever since the last update, about every ten games now i freeze when i am the host, i get host pretty frequently. this has never happened before just until the most recent playlist update. the game just completely locks up my ps3 and i have to cold boot it back up. also it sometimes host migrates and i'm the only one left in game, and then it goes to a forfeit. this only happens when i'm host.
i might note that this has NEVER happened to me before with any other COD including black ops 1, you can check my win/loss stats on elite for verification.
