(Is this where I ask this question?) Can craftmaster still be achieved on PS4 if I am in single player mode, get the wedding ring recipe and craft it in multiplayer, without having to craft all the items again? Thank you
I don't know about PS4, but on PC you don't need to craft the wedding ring to get the "craft everything" achievement, at least not if you're on a single player file. (Source: have never crafted wedding ring, have gotten achievement )
