I'm not quite sure if i found a bug or not in the update mechanism, could you maybe give me a small explanation what the values in the db mean
here my guess plz correct me if i'm wrong
id - Just a unique id for each entry PK
number - coords x/y
nodeNumber - resource type (iron, copper, etc.)
map - which zone ... tanaris, ashenvale, etc
nodeType - general type - herb, mining, others
continent - Kalimdor, eastern, Outlands
