March of the Lich King's launch day prologue bug

[Mountaineer-11770]

• [Added 12/6] The team is aware that some players are receiving the Death Knight prologue fights in the incorrect order. The team is investigating the issue. It appears players are still able to complete the prologue and unlock the Death Knight Core Set cards even if the fights are out of order.
• [Added 12/6] The team is aware that some players are getting stuck after winning the last fight of the Death Knight Prologue. Restarting the client will get you “unstuck.” If the Achievement has appeared for completing the fight, the player should be counted as having completed the prologue and unlocking the Death Knight Core Set cards.
