So, i took Serana to Throat of the World, and used the Ice Form shout on her. When she went down the mountain she started to fly around (as expected), but i were unable to find her later.

Ive tried spawning her in, but then i wont be able to talk to her. I also tried to wait for her and go to Fort Dawnguard, but nothing. Any help to get her back from her trip to wherever shes gone would be appreciated.

EDIT: Whilst i were messing around, she came back, no help required anymore. Thanks for the help tho!

Try that: Use the console, and type:

prid 02002B74

enable

moveto player

The prid 0200B74 command didnt work, only got "item '02002B74' not found for parameter ObjectiveReferenceID"

Depending on your load order, whether you use the unofficial patches, etc., the first two numbers (xx) in the reference (xx002B74) may be different. The correct reference for Serana may be 03002B74 (as shown in the example below), because she is added by Dawnguard.esm.

An example load order:

00 Skyrim.esm

01 Update.esm

02 Unofficial Skyrim Patch.esp

03 Dawnguard.esm

04 Unofficial Dawnguard Patch.esp

05 Hearthfires.esm

06 Unofficial Hearthfire Patch.esp

07 Dragonborn.esm

08 Unofficial Dragonborn Patch.esp

well, maybe. I Hope anyway. !!!! lol

I found those codes over the net.

prid xx002B74moveto player

Note that the xx has to be replaced by a number, usually one of 01, 02, 03 depending on the DLCs installed. You can also use help Serana to figure out the correct value.
