I am trying to save the UUID of a player to the NBT Data of a TileEntity, and it writes it(I even checked it with NBTExplorer), but it doesn't load it on startup of the world. All other NBT Data loads in correctly.

My Tileentity

    public NBTTagCompound writeToNBT(NBTTagCompound nbt) {
        super.writeToNBT(nbt);
        if(!name.equals("bulkcore")) writeItems(nbt);
        writeKeys(nbt);
return nbt;
    }
void writeKeys(NBTTagCompound nbt){
        if(name!="bulkcore") writeItems(nbt);
        if(owner!=null) nbt.setUniqueId("owner",owner);
        nbt.setBoolean("locked",locked);
        System.out.println(nbt.getUniqueId("owner"));
        if (this.hasCustomName()) nbt.setString("CustomName", this.getCustomName());
        for(int i=0;i<keys.length;i++){
        	nbt.setInteger(keys[i],this.getField(i));
        }
}
    public void readFromNBT(NBTTagCompound nbt) {
        super.readFromNBT(nbt);
        if(nbt.hasKey("owner")){
        	this.owner=nbt.getUniqueId("owner");
        if(nbt.hasKey("locked"))
        	this.locked=nbt.getBoolean("locked");
        }
        if(nbt.hasKey("CustomName")) this.setCustomName(nbt.getString("CustomName"));
        for(int i=0;i<keys.length;i++){
        	String key=keys[i];
            if(nbt.hasKey(key)) this.setField(i,nbt.getInteger(key));
        }
        NBTTagList list = nbt.getTagList("Items", 10);
        for (int i = 0; i < list.tagCount(); ++i) {
            NBTTagCompound stackTag = list.getCompoundTagAt(i);
            int slot = stackTag.getByte("Slot") & 255;
            this.setInventorySlotContents(slot, ItemStack.loadItemStackFromNBT(stackTag));
        }
    }

Does it print it out when it is writing? Try printing out when reading.

when it is writing it prints out the correct UUID, and then when I look into the Chunk Data into the TE NBT with NBTExplorer it is saved there.

When I put this

System.out.println(nbt.hasKey("owner"));

into the readFromNBT method, it always returns false...

Does anything else get loaded?

yes, everything else gets loaded correctly, forgot to say that

Dude i did...

BUT I DIDN'T TURN ON MY BRAIN

Thanks!

I knew it would be a really dumb mistake again...
