I’ve been looking for a solution to this for years and I still have yet to find one. I’ve played through the game on PS4 and just recently started on my Xbox 1 (no mods and I couldn’t use console commands even if I wanted to) I’ve tried every follower, I’ve started new games, I’ve uninstalled and reinstalled. I’m going insane trying to get a follower to activate the pillar of sacrifice but nothing works. Does anyone know of a way to fix this WITHOUT console commands?! If not then please tell me how to install or enable console commands so I can get this stupid trophy? Please and thank you.
According to Gamefaqs:
I had problems with this too. Turns out that you have to use a non-essential follower (meaning that he/she can die). Dark brotherhood followers are invincible. I hired a merc from riften (there is one in windhelm too). After that, I told him to activate the pillar and after a little glitchy-ness on the part of the game's AI pathfinder, my merc was trapped.
