The Knight losing his power entirely (clips attached)
I think it may have had something to do with the timing of the pallet being thrown. I didn't try to break it, I simply tried to push through it and spawn my ghost on the other side of it. The power canceled out early as soon as I hit the pallet, and it got stuck. It stayed there for the remainder of the trial. I tried to get stunned out of it, didn't work. I pointed it out to some survivors and asked them if they saw it in post game, they didn't.
