I believe I've found a bug. I was fighting Alectyron with a group and got paralysis. I still had the effect when Alectyron died. In between paralysis stops, I mounted the white magitek armor and it went skidding along the surface like it too was paralyzed!
I made a video showing it here. Even after the effect ended, the machine would still skid. Only releasing from it and re-mounting made it walk like normal:
