Problem with Chunk Load Event

[TLHPoE]

I'm not sure what's causing the problem, but sometimes it skips out on chunks.

 

My mod is supposed to generate new structures and ores after the Ender Dragon is killed. When I return to the overworld, only some chunks have the new ores.

 

Chunk Load Event:

@SubscribeEvent
public void chunkLoad(ChunkDataEvent.Load event) {
	if(!event.world.isRemote) {
		World world = event.world;
		Chunk chunk = event.getChunk();
		NBTTagCompound nbt = event.getData();
		if(!nbt.hasKey(ReferenceRF.ID)) {
			nbt.setTag(ReferenceRF.ID, new NBTTagCompound());
		}
		nbt = event.getData().getCompoundTag(ReferenceRF.ID);
		if(!nbt.getBoolean("postDragon") && ServerProxyRF.getWorldProperty(world.getWorldInfo().getWorldName(), "hasDefeatedEnderDragon", false).getBoolean(false)) {
			nbt.setBoolean("postDragon", true);
			ServerWorldTickHandlerRF.chunksToGenerate.add(chunk);
		}
	}
}

 

Here's my World Tick Handler:

public class ServerWorldTickHandlerRF {
public static ArrayList<Chunk> chunksToGenerate = new ArrayList<Chunk>();

@SubscribeEvent
public void onWorldTick(TickEvent.WorldTickEvent event) {
	if(!event.world.isRemote)
		for(int i = 0; i < chunksToGenerate.size(); i++) {
			Chunk chunk = chunksToGenerate.get(i);
			for(int j = 0; j < 8; j++) {
				int x = (chunk.xPosition * 16) + event.world.rand.nextInt(16);
				int y = 128;
				int z = (chunk.zPosition * 16) + event.world.rand.nextInt(16);
				event.world.setBlock(x, y, z, Blocks.diamond_block);
				System.err.println("Generating at X: " + x + "|Y: " + y + "|Z: " + z);
			}
			chunksToGenerate.remove(i);
			System.err.println("LOADING");
		}
}
}

Hi

 

Just my guess: perhaps it doesn't need to reload all the chunks if you have moved to the ender and back to the overworld.

 

What happens if you save the game after killing the dragon, shut down the game, then restart and reload it?

I tried that, the only other thing I noticed was that if I selected the world, it would return to the world selection menu. After a couple of seconds, it spawns me in the world. During that time, it said it was generating the stuff, but when I spawned nothing was there.

Hi

 

That's curious.  I don't see anything obviously wrong.  Perhaps the onWorldTick is being invoked too soon after the ChunkLoad.  I'd suggest you add some more logging to your world load event, to figure out whether the problem is in your ChunkLoad or onWorldTick.

Ok, I think I've found the problem.

 

 

For some strange reason, the ChunkDataEvent.Load doesn't always get called.

Update: I found an event (ChunkWatchEvent.Watch) that gets called when a chunk is loaded, but I can't get the NBT of the chunk or even tell if I've gone through it yet.
