This fixes an issue with plugins using legacy materials, spigot does not populate the bukkit registry properly, leading to NPEs when using outdated plugins. This patch should likely be dropped when spigot fixes their legacy data usage.... Also rebuild patches because 10/10

Subject: [PATCH] Fix items vanishing through end portal
|
|
|
|
If the Paper configuration option "keep-spawn-loaded" is set to false,
|
|
items entering the overworld from the end will spawn at Y = 0.
|
|
|
|
This is due to logic in the getHighestBlockYAt method in World.java
|
|
only searching the heightmap if the chunk is loaded.
|
|
|
|
Quickly loading the exact world spawn chunk before searching the
|
|
heightmap resolves the issue without having to load all spawn chunks.
