If you are kinda lost, I recommend you to read the Devlog of the updates to see what is new and what changed, and then you decide if you'll start it again or not.
Thank you for the advice! I've checked the updates and I think there's nothing special I have to replay, I've recently started the werewolf quest with Logan etc. and there's just the quest at the junkyard that I need to continue
I haven't reached Northcrest yet so I think I won't have any problems updating the game.
thx a lot xxxx
