Every time I use the module inserter, I get a blueprint, or something like it, in my inventory, eventually filling my inventory with module inserter blueprints. I use a void chest to periodically dispose of them, but it's a bug of some kind.

You can delete them by right clicking on the item and then clicking the trash icon in the top right.

The latest version will first take a module inserter from your inventory before creating a new one.

Is there some way to disable the item showing up in the inventory at all? As all the items are identical there's no reason I've found to not just use the hotbar button.
