When first loading into the game or changing zones, the "Rubies" are no longer attached to the terrain on the mini-map.
Workaround: Reload your UI. If that does not solve the issue, open the configuration (Game Menu->Interface->Click the AddOn's tab->Click Bloodhound->then Herbs or Minerals) then disable (click "None") all of the nodes. Then enable the nodes (click "All" or choose the node type you want to track).
Bloodhound AddOn options for Herbs and Minerals are not attached to the "Bloodhound" option in the interface panel and appear to be attached to another AddOn.
Workaround: The configuration options still work even though the Herb and Minerals options appear to be attached to another AddOn. This will be fixed in a future patch.
There is currently no node tracking on The Wandering Isle. This will be addressed in a future release.
This is a low priority issue as once you complete the initial Pandaren quest line and choose a faction you are likely never to see this area until you roll another Pandaren.
