Yeah about 3/4 of way through so i could branch off to any of the other alliances in the game and witness that path. Before that there isnt that many game altering choices you can make so didnt see point in fully starting over just yet.
Right, my point being that if you had done multiple full playthroughs from start to finish, then you would have definitely come across many of the bugs that so many people have been complaining about, myself included (though I've yet to make a major deal over it). Especially if you go the completionist route. There's well over 200 recorded glitches in the game, with their appearances ranging from common to extremely rare. I've encountered over 50 so far, and there's still a good portion of sidequests and locations I've yet to discover. Some of the glitches I've come across would have literally broken my playthroughs making them no longer playable had I not been wise enough to make a backup save of the same character before doing various quests.
For example, I currently have a glitch that has broken Arcade Gannon on my non-Hardcore Good save, where Arcade will no longer hold conversations with me, making it also impossible for me to trigger the unique quest for him. All I can do is command him through the companion wheel and trade equipment.
Hopefully this patch will fix majority of the issues people have been having, since it was mentioned on the official forums that this patch is a comprehensive one (unlike the one previous).
