[1.16.5] Error when save TileEntity data (ListNBT)

[Luis_ST]

As already stated in the title, I have problems saving my custom tileentity data,
the saving itself works, but when I change the data I close the world and open it again I get an error message (see log).

What I don't understand about it when loading the world,
the save method should not be called in my tileentity because the data should actually be loaded.
why is the method called?

 

this is my TileEntity
this is the log:

You are calling it yourself, here:

okay makes sense, but how do I prevent the tileentity data from being updated before it is not loaded?
in the forge doc to synchronize tileentity data it is checked whether the area is loaded, includes this also the data of the tileentity?

You increment i every loop, but only add to the ListNBT if the element is not null. So if for example the first element is null, on the 2nd loop i will be 1 and the ListNBT will be empty. You then tell the ListNBT to add at position 1, which it does not have (it's still empty). Do not use the add(int, T) method. Just use a normal foreach loop and add(T).

I had used add(i, T) to save the order of the list, but in the end it would not change anything in the function of the tileentity...
