The map of Gun and/or Gear using regions on p188 seems to mislocate all of the Garund locations. The Shackles are given a dot right next to Absalom in the inner sea, rather than being on the west coast of the continent. Dongun Hold and Quantium are both shown about half a continent too far south.
The Avistan sites seem to be mostly correct, but I don't know the other regions of the map as well, so I can't say with any confidence that these are the only errors.
