- Fix a typo (Taunka'lo -> Tunka'lo), and tell players that Lake Wintergrasp must be controlled by their faction to visit Elder Bluewolf.
- Whoops, missed a subzone -> zone change in the Horde guide.
- Swapped the Elders of Silithus around in the guide.
- Add an ugly fix to hopefully get rid of "table index is nil" errors.
- Fix the Elder of Thunder Bluff (Proudhorn -> Ezra Wheathoof).
