Yesterday, before the latest patch, during Golgoroth fight me and another player got kicked at the same time to XMB with the OS error blue screen. Today, post patch, the game crashed in the first area while running on the way to the relic. Some people in the raid teams (from LFG) say that the same happened to them or someone in a previous team they were in, also with no apparent reason, just playing as normal, but that it became more frequent since last week. (Just for FYI, Bungie)
