Hi,
Since playing Cataclysm Classic, I’ve noticed that not all dungeons are showing when looking for specific dungeons in the Dungeon Finder tool. Also dungeons are disappearing before the level range has been reached. For example one of the Scarlet Monastery dungeons is available in DF from levels 28-38, however when I reached level 32, that dungeon is now gone.
It looks like there was a hot fix for this in the past Classic expansions, however now this is happening again in Cataclysm.
