I don't know about the PS4 or PC, but on the Xbox One it seems that a lot of the quests I keep trying to do will have me go talk to a person, and they are not there. It will give me the option to talk to them, but they are missing and nothing happens when I hit the action button. Does anybody else have this issue? Has anybody heard about an update to fix this?
Quit out of the game turn the console off and wait for five minutes when you start the game back up the npc should then be working properly. Theres a thread here on their official forum about console issues and future patches.
