I would very much like some spoiler-filled response because I swear to God if I have to reset my save file AGAIN, I'm not going to be too happy. I have 55h on this savefile alone and while I understood reseting for the update, reseting because of this is going to be ridiculously frustrating.
Resetting your save file won't alter that. The big thing people are noting about the Nameless event is that one of the times he asks you a question, that question becomes locked to your computer and cannot be altered.
So there's no need to reset your save file for anything (In fact that literally /won't/ do anything, haha), just whenever he asks you a question make sure you select the response you mean to select the first time, rather than expecting to be able to reload back and tweak things.
