It appears that mods like Amazing follower tweaks and my home is your home erroneously sets the "Uses Stored Text" flag on its aliases without specifying a replacement "Display Name". This breaks SKSE's SetName function, which this mod uses, causing the NPC to have an empty name, which prevents interaction.

Alternatives to AFT:

• Simple Follower Extension (ignore the "AE" label. This mod works for all versions of Special Edition, despite its name)
• Nether's Follower Framework

Q: My mod manager says this mod has conflicts with another mod regarding "uilib" files.
A: This mod uses SkyUILib for some UI functionality. Chances are, your other mod uses the same files. If their version of the files are up-to-date, it is fine to have either mod overwrite the other for these files.

Q: What body type does she use?
A: She uses whatever body type you have installed. Included in the mod are UUNP, CBBE, and vanilla compatible textures; the armor come in CBBE, UNP, and vanilla shapes; pick the appropriate body type in FOMOD. The Armor also ships with both CBBE and UUNP bodyslides, so use those if you have custom body shapes.

Q: How do I enter and leave the player home or maze?
A: Click on the Dwemer Storage Box or the Dwemer Puzzle Box in your inventory to enter or leave.

Give her a place to live and some gold to buy clothes before she regains her memories. Talk to her in a home location to set home. Talk to her in a city exterior or store to buy clothes.

A: Jump over the bridge.

Q: Where can I find Elves for parts?

Q: Is there a LE (Old Skyrim) version?
A: Gameothic has kindly made a LE port. I am in no way responsible any issues that may arise from the usage of this backport. Only the SSE version is official supported.

Q: Can I upgrade?
A: All my mods are safe to upgrade whenever unless otherwise stated.

Problem: The sky looks like the inside of the box when I am outside!
Explanation: This is a known issue with the vanilla game where sky statics are not cleaned up consistently. This is the same issue that causes Apocrypha sky to sometimes show up outside Apocrypha. This should go away if you restart Skyrim or if you just play long enough for the game to cycle in some new weathers.

Problem: The Snow Elf says she's gonna fight me but doesn't!
Explanation: If you are using a follower management mod to recruit her, then her aggressive package might have been overwritten by such mod. You can still complete the quest, but you'll just have to beat a peaceful opponent.

Problem: The Snow Elf is stuck on some terrain!
Explanation: NPCs in Skyrim use navmeshes to pathfind and navigate around the world, and they will attempt to walk in places the navmesh says it is ok for them to walk. If a navmesh says an area is passable but there is actually an obstruction, NPCs will get stuck. This mod actually makes very few changes to navmeshes in the open world and mostly in out of the way places in Blackreach and Solstheim. Chances are the areas she's stuck in are not navmeshed very accurately to begin with, which is an unfortunately problem when playing with followers.

Problem: Incompatible with po3's Enhanced Reanimation
Explanation: it's currently incompatible with the horse patch. Turn this option off in the enhanced reanimation ini: "Patch Horses = false."
