Ok so got to the last section of the siege where you have to defeat the trolls before they break the door well I failed. After I failed it showed be for a brief moment where I couldnt do anything and faded to red and said failed. It did this a couple more times and I couldnt pause or anything so I quit out via PS button and restarted. I get back in at the start of the siege but there are no enemies so now I cant really do shit. Do I really have to fucking restart my game or can I get on a friends game from this point, get past then quit after it saves after that?
