[1.12.2] [SOLVED] Getting <Chunk> capability data

[GooberGunter]

So, I have an Item, when it is right clicked it fetches the capability data stored in the player's current chunk:

Spoiler

public ActionResult<ItemStack> onItemRightClick(World worldIn, EntityPlayer playerIn, EnumHand handIn)
    {
        //TODO sense arcana
		if(!worldIn.isRemote) {
			Chunk chunk = worldIn.getChunkFromBlockCoords(playerIn.getPosition());
			Chunk chunk2 = Minecraft.getMinecraft().world.getChunkFromBlockCoords(playerIn.getPosition());
			IArcana a = chunk.getCapability(ArcanaProvider.ARCANA_CAP, null);
			IArcana a1 = chunk2.getCapability(ArcanaProvider.ARCANA_CAP, null);
			int[] s = a.getArcana();
			int[] s1 = a1.getArcana();
			int f = s[0];
			int ai = s[1];
			int ea = s[2];
			int w = s[3];
			int ar = s[4];
			
			int f1 = s1[0];
			int ai1 = s1[1];
			int ea1 = s1[2];
			int w1 = s1[3];
			int ar1 = s1[4];
			playerIn.sendMessage(new TextComponentTranslation("Fire: "+f+" Air: "+ai+" Earth: "+ea+" Water: "+w+" Arcana: "+ar));
			//Util.logger.info("Fire: "+f+" Air: "+ai+" Earth: "+ea+" Water: "+w+" Arcana: "+ar);
			playerIn.sendMessage(new TextComponentTranslation("TEST Fire: "+f1+" Air: "+ai1+" Earth: "+ea1+" Water: "+w1+" Arcana: "+ar1));
		}
		return new ActionResult<ItemStack>(EnumActionResult.PASS, playerIn.getHeldItem(handIn));
    }

 

However, while I was testing some gui code that also fetched the same data, I noticed a difference in the result leading to the above test.

 

In the first test, I get an instance of the Chunk from the worldIn object

In the second test, I get an instance of the Chunk from Minecraft's (I think it's called a singleton) main world instance

I then print both and get two different outcomes. 

 

Question: Why are they different? Can I just run my code (i.e. subtracting and adding to the chunk capability) based off of Minecraft::world without any consequences?
