They disappeared?!

[Harladar]

I was just using gatherer, I use it all the time, and I have all the options for them to display on my main map, and minimap, I was admiring my finds in badlands for everything, I must have had close to 300 nodes of either plants, or veins, and I moved onto the next zone, I use gathershare, everyone in my guild does. So, I goto the next zone, and keep on going, then someone in the guild who doesnt have gatherer ask where they can find mithril, I say badlands, and tell them where, I pull up the map of badlands, and nothing is there, no veins, plants, nothing, i checked my setting and everythings cool, whats going on?
