+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.
