Subject: [PATCH] Detect and repair corrupt Region Files
|
|
|
|
If the file has partial data written but not the full 8192 bytes,
|
|
then the server will be unable to load that region file...
|
|
|
|
I don't know why mojang only checks for 4096, when anything less than 8192 is a crash.
|
|
|
|
But to be safe, it will attempt to back up the file.
