Nostalrius Begins - Quality wow vanilla realm (1.12)

Door to the ramp to last boss was open at start, we summoned and killed the stone guards anyway (the room with the altar) and everyone in the groups heart sank when after hours of forming the group and PVP to make it into the instance, the door to the last boss CLOSED, locking us out from finishing.

I don't know why this doesn't have more comments. I just did Uldaman today and can vouch that this bug is still happening.
