Years ago, Arcimaestro Antares made a creature version the Luggage on my request and I released a little pack mule mod with it. I've finally fixed its scripts and taken the thing out of beta.
I think I finally fixed the problem with my MWSE companion scripting. If someone could test it out and let me know how well it works, I'll finally be able to fix the MWSE scripting for the Uvirith's Legacy companions as well.
If you don't want the Luggage to be able to follow you anywhere, just use the base mod. The base mod is compatible with Mel's Teleport Mod. The MWSE version circumvents it for its own scripting.
