[1.15] Data not being transferred from ChunkDataEvent.Save to Load

Hi!

 

I'm trying to store an int amount of specific fluids into the chunk data, and I believe the chunk is being saved correctly (using ChunkDataEvent.Save), however it is not present when trying to load NBT from ChunkDataEvent.Load. Any push in the right direction would be wonderful.

 

@SubscribeEvent
	public static void chunkLoad(ChunkDataEvent.Load event) {
		
		if(event.getWorld() != null && !event.getWorld().isRemote()) {
			FluidLevelManager.readData(event.getChunk().getPos(), event.getWorld(), event.getData());
		}
	}
	
	@SubscribeEvent
	public static void chunkSave(ChunkDataEvent.Save event) {
		if(event.getWorld() != null && !event.getWorld().isRemote()) {
			FluidLevelManager.writeData(event.getChunk(), event.getWorld(), event.getData());
		}
	}
	
	@SubscribeEvent
	public static void chunkUnload(ChunkEvent.Unload event) {
		if(event.getWorld() != null && !event.getWorld().isRemote()) {
			FluidLevelManager.clearData(event.getWorld(), event.getChunk().getPos());
		}
	}
public class FluidLevelManager {

	
	public static final ConcurrentHashMap<ChunkCoords, FluidStack> CHUNK_FLUIDS = new ConcurrentHashMap<>();
	
	private static final Random RAND = new Random();
	
	public static void readData(ChunkPos pos, IWorld world, CompoundNBT nbt) {
		
		ChunkCoords cc = new ChunkCoords(world.getDimension().getType().getId(), pos.x, pos.z);
		if(nbt.contains("assemblylinemachines:chunkfluid")) {
			
			CHUNK_FLUIDS.put(cc, FluidStack.loadFluidStackFromNBT(nbt.getCompound("assemblylinemachines:chunkfluid")));
				
			
			
		}else {
			
			int val = RAND.nextInt(40);
			
			
			if(world.getDimension().getType() == DimensionType.OVERWORLD) {
				
				
				if(val == 0) {
					CHUNK_FLUIDS.put(cc, new FluidStack(Registry.getFluid("oil"), (RAND.nextInt(4000) + 1001) * 1000));
				}else if(val < 4) {
					CHUNK_FLUIDS.put(cc, new FluidStack(Fluids.LAVA, (RAND.nextInt(11500) + 1001) * 1000));
				}else {
					CHUNK_FLUIDS.put(cc, FluidStack.EMPTY);
				}
			}else if(world.getDimension().getType() == DimensionType.THE_NETHER) {
				if(val < 7) {
					CHUNK_FLUIDS.put(cc, new FluidStack(Fluids.LAVA, (RAND.nextInt(29000) + 1001) * 1000));
				}else {
					CHUNK_FLUIDS.put(cc, FluidStack.EMPTY);
				}
			}
		}
	}
	
	public static void writeData(IChunk chunk, IWorld world, CompoundNBT nbt) {
		ChunkCoords cc = new ChunkCoords(world.getDimension().getType().getId(), chunk.getPos().x, chunk.getPos().z);
		if(CHUNK_FLUIDS.containsKey(cc)) {
			
			CompoundNBT sub = new CompoundNBT();
			CHUNK_FLUIDS.get(cc).writeToNBT(sub);
			nbt.put("assemblylinemachines:chunkfluid", sub);
			
		}
	}
	
	public static void clearData(IWorld world, ChunkPos pos) {
		int dimid = world.getDimension().getType().getId();
		CHUNK_FLUIDS.remove(new ChunkCoords(dimid, pos.x, pos.z));
	}
}

 

No matter what, the two prints at the top of readData always output 0 and an empty string.
