I have a mod that brings a follower (Jessica) in the game. It is good, she is not too overpowered (as far as I can tell), but there comes the problem.
I was exploring the ruins of Arkghthand (or whatever) and found the puzzle box. On my way out, on the very top of the stone ledge, ten meters before exit, she falls. She cannot step on the final ledge. I tried everything I could think of, to no avail. Help needed. A console command, a spell, anything that could bring her half a meter up. I am loaded with gems, and don't want to have to play the dungeon again.
BTW, she can cast two spells: Water Breeding and Water Walk. no much of a help here.
