Minecraft – How to get rid of an Unstable Node quickly

minecraft-feed-the-beastminecraft-java-edition

So I'm an admin of a minecraft server, and I've discovered that the wisps near my server's spawn arn't just the result of a spawner, there is actually a very large (over 500 vis) unstable node about 100 meters from the spawn area generating them. This is causing all kinds of issues as I have people joining the server and getting practically insta-gibbed by a swarm of wisps. How can I get rid of the node quickly?

(I'm using Thaumcraft 3)

First, make note of the node's position in the world.

Using this: http://dinnerbone.com/minecraft/tools/coordinates/

Find the chunk and region file that the node is in, and take note of them.

Then:

  1. Stop the server ( maintenance weekend! )

  2. MAKE A BACKUP OF THE WORLD!!!! (just in case, Murphy is watching)

  3. Using NBTExplorer, or a similar program, open the region file who's name you took down earlier (it will be in SERVERFOLDER/WORLDFOLDER/region/)

  4. Locate the chunk in the file that your node is in, I find it helpful to put something obvious there so I can find it later, like a named mob, whose name I can search for to find the chunk.

  5. Look in the TCNODES section of the chunk, here is where thaumcraft stores it's nodes.

  6. you can just delete the node in it's entirety, or you can set it's type to 1 (pure node) and delete all entries under Flux.

That's all there is to it.

You can now go on a whisp-killing-spree!!!
