User blog comment:JackFrost23/New RDR Update 6/11/14 Apparently Has Multiplayer Fixes/@comment-26085851-20140612182555

RDR multiplayer has appeared to return to normal. On a side note, after booting up Undead Nightmare, the War Horse was unlocked for me.

Quote from Game: "Warhorse Unlocked. This horse is fatser and stringer than all but the rarest of wid stallions."

The Leaderboards are also gone and I assume, the Social Club challenges and cheats to be unlocked are gone too.

Long Live RDR.
