Console: XBOX 360
Yes the system downloaded a patch on the first use.
Playing in split screen coop/single player.
I was first experiencing the coop desync glitch when myself (using an online profile as host) and my girlfriend (using an offline profile) were playing. On reaching chapter 4 prologue and saving it showed her character as still in chapter 3 part 1. I back tracked with her character in single player to try to bring it back up even with mine and it showed as not even having the chapter 2 quests completed. Upon trying to recomplete the Barrow Downs her character is loaded after the last checkpoint prior to the boss wight, where the door to the previous portal is sealed behind you. The boss will not spawn after reaching the location, leaving the character trapped in this area and unable to go anywhere else.
