OneAdapter: Invalid view holder adapter position

Hi, the library is really great due to its modular design. It really does help a lot.

Unfortunately I have encountered an issue. I will first show some code, but I do not have a small, executable example at the moment, I might add it later.

My code uses the OneAdapter as follows:

Within the fragment:

recyclerView = view.findViewById(R.id.ingredients_list);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
oneAdapter = new OneAdapter(recyclerView);
oneAdapter.attachEmptinessModule(new PantryEmptinessModule());
oneAdapter.attachPagingModule(new PantryPagingModule());
oneAdapter.attachItemModule(new PantryItemModule());
prepopulateAdapter();

Within prepopulateAdapter (on main thread):

oneAdapter.add(recipes); //recipes is an ArrayList

Within PantryPagingModule:

@Override
public PagingModuleConfig provideModuleConfig() {
    return new PagingModuleConfig() {
        @Override
        public int withVisibleThreshold() {
            return 3;
        }
        @Override
        public int withLayoutResource() {
            return R.layout.load_more_item;
        }
    };
}

@Override
public void onLoadMore(int i) {
     //Recipes are obtained in the background...
     //on main thread
      oneAdapter.add(recipes); //recipes is an ArrayList
}

The item looks as follows:

@PrimaryKey
    public int id;

    @ColumnInfo(name = "name")
    public String name;

    @ColumnInfo(name = "amount")
    public int amount;

    @Override
    public boolean areContentTheSame(@NotNull Object o) {
        if (!(o instanceof Recipe)) {
            return false;
        }
        Ingredient other = (Recipe) o;
        boolean names = this.name.equals(other.name);
        boolean amount = this.amount == other.amount;
        return names && amount;
    }

    @Override
    public long getUniqueIdentifier() {
        return id;
    }

And the error message that sometimes comes when scrolling is:

ava.lang.IndexOutOfBoundsException: Inconsistency detected. Invalid view holder adapter positionViewHolder

Now, I have no idea where this error might come from. Maybe we can find a solution to this and fix it. If any more information is needed, I’ll be happy to help. Thanks in advance.
