I am getting this on a save (Jossie) that has not even stepped into the Skull Caverns yet. I did not see it on a save (Ked) that had been in there. I have not gone to the caverns yet on Ked to see if the elevator worked. Ked previously dropped to level 25, then I added the mod. I was on Ked after that, but played on Jossie today.
