From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Aikar Date: Tue, 31 Mar 2020 03:01:45 -0400 Subject: [PATCH] Fix unregistering entities from unloading chunks CraftBukkit caused a regression here by making unloading chunks not have a ticket added and returning unloaded future. This caused entities who were killed in same tick their chunk is unloading to not be able to be removed from the chunk. This then results in dead entities lingering in the Chunk. Combine that with a buggy detail of the previous implementation of the Dupe UUID patch, then this was the likely source of the "Ghost entities" diff --git a/src/main/java/net/minecraft/server/WorldServer.java b/src/main/java/net/minecraft/server/WorldServer.java index fca8194f27d5a8707296600bca7027a80c13877c..59afafecabd59ede1398c124769262f7568426ed 100644 --- a/src/main/java/net/minecraft/server/WorldServer.java +++ b/src/main/java/net/minecraft/server/WorldServer.java @@ -1386,9 +1386,9 @@ public class WorldServer extends World implements GeneratorAccessSeed { } private void removeEntityFromChunk(Entity entity) { - IChunkAccess ichunkaccess = this.getChunkAt(entity.chunkX, entity.chunkZ, ChunkStatus.FULL, false); + Chunk ichunkaccess = entity.getCurrentChunk(); // Paper - getChunkAt(x,z,full,false) is broken by CraftBukkit as it won't return an unloading chunk.
