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.
