RDR has suffered from many glitchers in its time. But as of the release of Myths and Mavericks along with a dlc patch, these glitches no longer exsist. Rockstar has personally seen to the matter and has corrected these error codes to prevent players from having an unfair advantage. As of now, the invincibility, the flying and walking on air, and freezing xbox's glitches have been patched. Red Dead has returned to its former glory thanks to the Rock Star Tech Team. Now no-one has to worry about these little problems.
