While visiting my brothers house for Christmas I borrowed RDR: Undead Nightmare from my nephew.  When I started the game I had this glitch that is in the video.  It swaps around character models in some unique ways.  The problems arise when you have to hog tie certain characters that are swapped out with dead mountain lions.  You can't hog tie the dead mountain lion making it impossible to get past that sequence.  After some googling and scouring some youtube comments sections I figured out how to solve the problem.  I hadn't played RDR in a long time and it had an older patch after updating the main game I was good to go.  Figured I'd toss this up on the site so that any one else that stumbles across this glitch just might come across this article and find the solution a little bit quicker than I did.
