I need to find an npc but somehow the npc isnt there anymore. She is supposed to be in that location always and now she isnt.

I know there is a console command to teleport NPC to you, but how do i teleport myself to the NPC?

The NPC is serana. I finished the dawnguard and she is always in the fortress, but today she isnt there. I searched for hours but she is gone. I think it is because i uninstalled amazingfollower tweaks. Now i need to find her exact body(not player.placeatme)

So how do i teleport myself to her?

prid [REF ID GOES HERE]
moveto player

That's the one that moves her to player, to move yourself to her use

player.moveto

Mind you that it's possible she is out of the playable game area, so save before trying that.

(Serana's RefID is xx002B74 where xx is the load order of Dawnguard.esm, usually 02).

Just realised I mis-read the question, my mistake
