Light and heavy oil to sulfur can't use productivity modules.

Add this to the end of your data-update.lua to register the new recipes with productivity modules.

for k,v in pairs(data.raw.module) do
  if v.limitation then  
    if data.raw["recipe"]["heavy-sulfur"] then 
      table.insert(v.limitation, "heavy-sulfur") 
    end
    if data.raw["recipe"]["light-sulfur"] then 
      table.insert(v.limitation, "light-sulfur") 
    end
  end
end

 
PS: You toggle light-sulfur on and off so often it's hard to make changes to your code.

I won’t be able to take a look until Monday, but the light and heavy recipes should be direct copies of the vanilla recipe.

Productivity module restrictions are in a table separate from recipes.
You have to whitelist each recipe by name in it for prod modules to be allowed.

Ah, ok. Didn’t know that existed.

Cripes... completely forgot about this. Must've been about the time I stopped playing.

This is now done.
