This chunk was persistently regenerating inside a build every few hours.

So recently on my server (Creation Bay) we had an issue regarding what appeared to be a corrupted chunk, every 6-10 hours it would regenerate itself completely and as though this wasn't annoying enough it was right in the centre of quite a large build site.

A few of my players banded together and spent some time working out how to go about fixing this issue permanently, and I am happy to say that through their efforts a solution was found! As it turns out fixing corrupted world chunks is quite easy, you just need the right tools to do it.

In order to fix a corrupted chunk you need 2 things:

1) MCEdit (A free world editor for Minecraft, just type it into your preferred search engine and you will find it no worries, there are also tonnes of tutorials and "how-to" videos as well should you need a hand working out how to use it.)

2) The world file that contains the corrupted chunk.

Once you have these 2 things the next part is a piece of cake, simply open the world file that has the chunk issue with MCEdit. Press these keys- "Ctrl+I" and then select the option of "region repair" (Or something along those lines, I cannot remember exactly what the option is called, but it is only 1 of 2 options that are available.) and then let it work its magic!

Re upload the file to your server or open it in Single player (depending on how you play I suppose lol) and it should never bother you again. I have personally tried this method and it is safe to say it has been a success for me and my server!

I have written this article as this issue caused me and a number of my fellow Creation Bay users quite a headache and stress, and I hope that if you are suffering this issue you stumble across this article and find it helpful :)

Thanks everyone, take care and happy crafting! :D

The problem for me is that there are apparently over 200 chunks like this, and every time a player joins the server in one of those chunks the server just crashes. So I'm not sure where all these chunks are located.
Is there a way to do a global chunk fix?

Thanks for helping! I was able to save a world that was hard-worked on with this tutorial.

Thanks :)
It's also worth noting that you of course have to open your world in MCEdit first

This works wonders for a small world, sadly my world is nearly 4gb and takes forever to load in MCEdit...

Yeah, I know what you mean. I did this fix back when the CB world was only about half a gigabyte, now days the world file is well over 6gb.

Two questions:
1. Does this work for 1.4.6
2. Did you ever see an issue with players crashing the server when joining on a world with corrupt chunks? I've been having this issue for over a week and would really like some feedback.
Thanks! :D
