-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.
