This +patch is for mitigating those issues by various methods. + +Also fixes correctly marking/clearing the entity generation flag. +This patch sets the generation flag anytime an entity is created +via StructureTemplate before loading from NBT to catch uses of +the flag during the loading logic. This patch clears the generation +flag from an entity when added to a ServerLevel for the situation +where generation happened directly to a ServerLevel and the +entity still has the flag set. + +diff --git a/src/main/java/net/minecraft/server/level/ServerLevel.java b/src/main/java/net/minecraft/server/level/ServerLevel.java +index c5e404dcdab14dc0b972aa3286b05e21d9ea67e0..aaaf5b91402a1562311dfdc287193a1aefbaf9a7 100644 +--- a/src/main/java/net/minecraft/server/level/ServerLevel.java ++++ b/src/main/java/net/minecraft/server/level/ServerLevel.java +@@ -1224,6 +1224,7 @@ public class ServerLevel extends Level implements WorldGenLevel { + // CraftBukkit start + private boolean addEntity(Entity entity, CreatureSpawnEvent.SpawnReason spawnReason) { + org.spigotmc.AsyncCatcher.catchOp("entity add");
