OK so I've been playing a private DW20 server for some time.  One of the things I accomplished was to create a pure node (about 1200) by use of Silvewood trees and combining it other smaller nodes.  Now however, I have a few of the smaller nodes that are always in high or moderate flux.  They will not drain the flux away naturally.  I initially thought it was due to a nearby dark node.  Not the case and that dark node is now gone (one of the nodes I absorbed to get the pure node) and still this same node stays at high flux.  Any ideas?  Do nodes at high flux occur naturally or have I messed up aura by what I've done?
