Hi! Thanks for reporting, made version 0.1.2 that shall fix that issue – please have a try and tell if that helps 🙌

Hey looks like you changed the Factorio version to 2.1 in the info.json. When I changed that back it now give me this:

Failed to load mods: deadlock-beltboxes-loaders/prototypes/create_stack.lua:65: attempt to perform arithmetic on field 'icon_size' (a nil value)
