I figured it out. Turned out my quicksave was corrupted somehow. Notice in the video, the nameless one's companions aren't on the floor, that was the problem.
Luckilly I had a backup save on that exact area. Loaded it up, companions were now on the floor, it worked, beat the game, awesome stuff. I'll link my non-corrupt save below if anyone in the future has the same problem but doesn't have a save to fall back on. I bundled a char editor with it so you can rebuild your character.
