I finished the story battle at Dugoula pass. I had added a few new guys to my party and needed to let a few go. I was scrolling through my guys to pick one and came upon one of my Dark Knights. I noticed that his image was just a little bit off. After I got my group numbers right I checked and his image had gone back to normal. Not a bug that effects game play, but I still figured I should toss it out there.
