Disabling prime spidertron option in mod settings causes an error on load:

Failed to load mods: ...rProject__/spidertrons/spider_technology_definitions.lua:190: attempt to index field '?' (a nil value)
stack traceback:

Thanks for the report! I have fixed the logic and it loads on my machine right now. I have uploaded a new version that should appear in the game soon. Do let me know if anything else breaks.
