ForgeFlower is better than Spigots FernFlower at decompiling the source. However, in order to maintain the CraftBukkit patches, we must keep using spigots for the primary. However, for any file that we import on top of Spigots imported files there is nothing stopping us from using better decompiled files. So these changes will use ForgeFlower to maintain a better set of decomped files, so anything we add on top of Paper can start off in a better spot.

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.
