Solved Chunk file .. is in the wrong location; relocating.

[Z32]

Appears to be a chunk that is corrupt?
After a player logs in, the server will struggle to load surrounding chunks and freeze, while memory overflows and I get a 100MB+ log file

I guess I should mention,

Narrowed this down to region r.1.0.mca
Aka the area of about 100 hours of work
Still working on it, looking for a way to read and edit these files.

Following up on this;
One way to find the corrupted (or in my case, relocated) chunk, I deleted each region file one by one, opening the server to check if the problem persisted after the server regenerated the chunk via seed. r.1.0.mca contained my relocated chunk.

Another way, use Fenixin's Region fixer tool:
https://github.com/Fenixin/Minecraft-Region-Fixer
(Download the windows executable from that link)

Run the tool as seen in this post
http://www.minecraftforum.net/topic...n-fixer/page__st__20__p__4855777#entry4855777

For more options, type "region-fixer.exe --help" once you are in the region-fixer directory, to find more options and to replace or delete wrong located chunks (16x16 area)

For my instance, I need to type "region-fixer.exe --delete-wrong-located" and probably "region-fixer.exe --delete-entities" to fix 8 chunks which showed entity errors of over 300 entities (village overflow)

Cheers

I already knew of this fix. It annoys me alot though, It's happened to me about 13 times now. Except, this time, its took my home. Is there any possible way to use the region fixer to replace the Wrong located chunks with backups? I've tried and it simply reply's with:
Can't use this backup directory. Chunk has the status: Wrong-Located.
Used to happen in 1.4, too
