I was skimming through the Crown Store companions I've unlocked, and I noticed that Black Angus (a bison gunslinger, I think) has a small graphical glitch. At least in the crown store window. His mustache is twisted to one side. IE, the right side (his right side, anyway) sticks out from his face, and the left side is actually passing through the side of his face.
I have too many companions already, so I did not purchase him from the store to see if this is just a display error or if the actual character model is glitched. Which means I also don't know if it persists once he's promoted.
