From my reading, Productivity Modules are only to be used on Intermediate products.

In that case, why am I unable to place any productivity modules in assembling T2 machines producing Iron Gear Wheels?
When I try to insert Productivity modules on Iron Gear Wheels assembly machines manually (not through control - Click), I keep getting the message "Productivity modules are meant for Intermediate products, only"

Aren't Iron Gear Wheels an Intermediate product?

Thanks for the report however you can place them into assemblers producing iron gear wheels. Are you using any mods that may have changed things?

We are using mods, yes. However, this is not my game, therefore, I do not control which mods are included or not.

Are there any way to tell which Mod my have affected this?

ctrl + shift + e -> recipes -> iron-gear-wheel -> click on it and it will show which mods have changed that prototype.
