So I've been playing Fallout 4 for a while now ( I'm rank 36 ) and as soon as I came across the quest "Dangerous Minds" my whole game glitched and by that I mean I was doing the quest allright and then after I left Kellogg's mind, Nick Valentine wasn't in the memory lounger and had went back to Sanctuary, and whenever I tried to talk to him he just says "Sit down if you're ready to do this" and "Be careful when cruising through Kellogg's mind, I'm hooked up to it after all", so I'm just really confused as to what I should do, I've just been doing a lot of side quests to pass the time and would really appreciate it if anyone knew a way around this glitch. By the way I'm on PS4 so I don't think that console commands will work.

can you reload a prior save? That's really all i think you can do.

Now there's a glitch!

No previous saves?

If not, you may want to take some screenshots and post a report with Beth to see if they have a solution.

The previous save to that one is the one that's before i even went into vault 111 so i dont think i really want to restart my game :/

Haha...

(You're joking, right?)

Not being unkind, but the occasional issue is to be expected in such a huge game.

I try to do a 'hard' (non-quicksave) at least once per mission,

frankly to do less is really asking for trouble.

The 'save' feature is there for a reason.

No its not like that, i know i saved a load of times before it its just that they seem to have dissapeared, and it only shows my old "saves" not "quicksaves"
