The industry part of Advanced Autonomous Industries. Adds motors, powered offshore pumps, burner labs, and more. Alters tech and recipes. Additional features will be added gradually. Other AAI mods are not required.
But; productivity mods for making motors and electrical motors. (And engine units while we're at it.)
When trying to input productivity mods it specifically says "productivity modules are only useable on intermediate products." Which is the tab the motors (and engine units) are in.
What type of productivity module are you using? A vanilla one or bobs?
