whether it was set true or false,the Yuoki Productivity modules seems do not change, just like vanilla modules only can be used in intermediates recipes.

Can you please confirm what recipe you were expecting this to work on?

For clarification, prod modules usually only allow you to use them on low-level intermediates.
That setting just allows higher-level ones to have prod modules used.

As far as I can tell its working as expected?

maybe i was misled by this, i think change the behaviour to false,the yuoki prod mod could be like this.then i try to put them into a assembling-machine-2 making inserters,it could not work.
maybe i misunderstand what the setting does.

That setting just allows higher-level ones to have prod modules used.

i just do not know what can i recipe using the prod module when i setting it true,sry.could u give me a example?thx.
