when it happened to me, the swings would change with each change in stance, but they were jerky and unnatural. I could tell by the relative speed of the swing which stance I was in, but where the shields and health showed normally, the color for the stance was absent. It was unlike the default when you have no force in saber offense (which shows the yellow). This shows NO color.
BTW, I was not referring to the folder; that I know goes in the gamedata folder (and is the one that should be removed). I was speaking of the .pk3 file in base.
